   THE MARXMENU NAME   THE MARXMENU NAME   THE MARXMENU NAME

   When I first wrote this program my friends referred to it as Marc's
   Menu. That's where the name MarxMenu came from. It has nothing to do
   with either Carl or Groucho Marx.

   TECHNICAL SUPPORT   TECHNICAL SUPPORT   TECHNICAL SUPPORT

   Technical support for MarxMenu is provided several ways. The first is by
   calling our voice line 1-417-866-1222. We would ask that you not call
   the 800 number as that is for orders and ordering information only.

   We have several support staff and will try to answer your questions as
   quickly and efficiently as possible. We at Computer Tyme look at
   technical support as an opportunity to improve our product.

   We also have a 24 hour BBS system. This allows users with modems to
   leave messages about support issues. There are several user uploaded
   menus here and it serves as a forum for MarxMenu users to share ideas
   and techniques.

   Our BBS number is 1-417-866-1665. Supports 2400 baud but is 1200 baud
   compatible. Use 8 bits, no parity, 1 stop bit (8N1). You will also need
   to set your terminal emulation mode to ANSI or VT100.

   On our BBS are additional sample menu files that other MarxMenu users
   like yourself have uploaded. We encourage you to share your work with
   others so that yet more MarxMenu users can benefit.

   We are also available on Compuserve ID 76505,1120.

   We also offer a Priority Support Service which includes regular upgrades
   sent to you automatically as we come out with them. This doesn't mean
   every version of MarxMenu, but every so often after making several
   improvements and the product is at a stable point. The Priority Support
   Service includes special access to our support BBS.

   This service is for the very fierce MarxMenu user who has to have the
   "Latest and Greatest" all the time.

   OVERVIEW OF THE MARXMENU SYSTEM   OVERVIEW OF THE MARXMENU SYSTEM   OVERVIEW OF THE MARXMENU SYSTEM

   MarxMenu is not just another fill-in-the-blank menu system. It is a menu
   programming language and job control language. It gives you total
   freedom to do whatever you want, but total freedom has a price. You will
   need to know and understand how to use a text editor. This isn't
   difficult if you are familiar with using a word processor. And you will
   need to have a basic understanding of DOS and how batch files work.

   With a text editor you can create a menu file which is a text file with
   an MNU extension. Or, you can copy and then modify the text file
   SAMPLE2.MNU which displays the menus you see when MarxMenu is executed.
   This text file contains a set of instructions for MarxMenu to follow.
   MarxMenu will then read your menu file and run the instructions.

    A menu file might look as follows:



   Computer Tyme MarxMenu Users Manual                     Page 4
   _______________________________________________________________


    DrawBox 31 5 18 4
    UseArrows
    Writeln   '  W - WordStar'
    Write     '  L - Lotus'

    OnKey 'W'
       CD\WORDSTAR
       WS

    OnKey 'L'
       CD\LOTUS
       LOTUS

   The above example is a fully working MarxMenu program. Just because
   MarxMenu has 500 commands doesn't mean you have to use them all. The
   reason there are so many commands is that people keep calling me up and
   asking if I can add such and such. Most of the time I do. That's why the
   manual gets behind sometimes.

   The instructions must be from the vocabulary of words that MarxMenu
   understands. These words make up the command list included in this
   manual. They must be used precisely as the instructions in this manual
   tell you to use them. This process is called programming.

   I know that for many of you the word programming is a scary word. Put
   your fears at ease, MarxMenu is one of the easiest programming languages
   there is. It is a little harder than writing batch files and a lot
   easier than Basic. It requires a working knowledge of DOS and an
   understanding of writing batch files as explained in your DOS manual.

   The point that I want to make is, do not let the fear of learning and
   the fear of programming prevent you from learning to write your own
   menus. If you have never touched a computer before and are sitting down
   with your first PC, read the manuals first. Become familiar with the
   MS-DOS operating system. Learn how to write batch files, make
   subdirectories, copy files, format floppies, etc. If you don't
   understand something, ask a friend. All of us had to learn sometime, and
   there is no such thing as a stupid question.

   After you have mastered some of the basic concepts of the operating
   system, then learn either TEDIT or MarxEdit. These are text editors
   included with your MarxMenu program. Use it to write your own batch
   files. Then attempt to write your own menus by modifying the sample
   menus (files with a MNU extension) which come with MarxMenu. Print these
   menus and study them, referring to this manual for help on command
   definitions. You do not have to completely understand them to start
   making changes. Programming is a trial and error process.

   A computer, like a musical instrument, is only as good as the player.
   The more you learn about it the more you'll find it can do. In fact, a
   computer can help raise your effective IQ as you learn the disciplines
   of logic and reason. As a hammer is a tool of the hand, enhancing your
   physical strength, a computer is a tool of the mind, enhancing your
   mental strength. You will learn that as you develop a relationship with
   your computer, that you will be able to process information in ways you
   never dreamed.

   MarxMenu is an excellent learning tool. By the time you become
   proficient with the menu language, you will have learned the fundamental
   concepts behind the MS-DOS operating system. You will find yourself
   going back and forth between this manual and the DOS manual that came
   with your computer. When you master the language, you will have enough
   computing skills to be a real resource in your office environment. In
   this day and age, knowing how to "make the damn things work" is a key in
   moving up the corporate ladder.

   If you have sufficient excess income to afford a personal computer, or
   are in a job that provides you with a workstation, you are smart enough
   to learn this program. All it requires is that you take the time. You
   can do it. It is worth your time, and you will make up the time spent in
   the results you'll get. Good luck and enjoy.

   WHAT MARXMENU DOES   WHAT MARXMENU DOES   WHAT MARXMENU DOES

   So with hundreds of menus on the market, what makes this one so great.
   Well, let me tell you about it. MarxMenu is a menu language rather than
   a fill in the blank kind of menu. MarxMenu gives you total control of
   your computer system.

   It is also a job control language allowing you to program processes too
   difficult to do with batch files. MarxMenu can be used to do anything
   from overnight batch job processing to generating control scripts for
   mainframes.

   Because of it's simple syntax, MarxMenu makes an excellent teaching
   language putting more programming power in the hands of the student
   programmer than any other programming language.

   As a menu, MarxMenu can be as simple or as complex as you want. If you
   want simple, nothing is easier. If you want POWER, nothing is more
   powerful. If you want to get really weird, MarxMenu can do really wierd.

   So if you want the menu to remind you to go vote, MarxMenu knows when
   the first Teusday after the first Monday in November on even years is.
   If you are into Astrology, and you want certain menu items to appear
   only if Mars is in the right place in the sky, MarxMenu can calculate
   the orbit of Mars for you.

   _______________________________________________________________


   MarxMenu can be used to program games, write running software demos and
   online tutorial programs. It can be used to write testing programs. It
   can be used to write custom software installation programs. It can be
   used to assist other applications to make other software more network
   friendly.

   MarxMenu has a compiler for high speed execution. Even very large menus
   come up in under 4 seconds on a 4.77mhz IBM XT on an ArcNet lan. The
   compiler also provides security in that you can keep your source files
   separate so no one can alter the menu files.

   FOR THE POWER USER:   FOR THE POWER USER:   FOR THE POWER USER:

   I originally wrote MarxMenu on a dare. I said that in one afternoon I
   could write a better menu system than one of the most popular menu
   systems. I met the challenge and then found that there is a lot of
   demand for power in a menu system. Friends started asking for this and
   that feature and this program has gone far beyond what I ever intended.

   The demand for more features has outpaced my ability to keep up with the
   documentation standards that I expect from other software packages that
   I buy. Please bear with me. If you find any errors in the manual, or
   bugs in the program, please let me know and I'll try to correct any
   problems.

   I also appreciate your suggestions for improvements. Many of the
   features included are a result of requests you have made. Many of you
   are using this program in ways I never dreamed.

   The main design philosophy behind this product is POWER and Flexibility.
   I am also committed to keeping the source code as readable as possible.
   I am loyal to the concept of using NO RAM. None of MarxMenu stays
   resident. Because of this I can claim that if you are having some kind
   of problem, it's not the fault of MarxMenu being resident, because
   MarxMenu is not resident. Also, using NO RAM allows loading of TSR's
   (memory resident programs) from the menu.

   For computer consultants, MarxMenu is an excellent way to make money.
   You can provide your clients with professional looking menu systems
   customized (by you) to fit their needs. You can provide complex menu
   structures not possible with any other menu system. And, because
   MarxMenu uses NO RAM, you don't have to worry about conflicts between
   MarxMenu and any other software product.

   Although MarxMenu is copyrighted, the program is not copy protected.
   There is nothing to prevent you from making hot copies and giving them
   away to all your clients. I would like to point out that when you give
   away something you should be selling you lose respect from your clients
   and attract those who expect you to work for free. You will make more
   money if you play by the rules. My best and most profitable clients use
   no hot software whatsoever. Think about it.

   INSTALLATION   INSTALLATION   INSTALLATION

   You may wish to copy the MarxMenu system into it's own subdirectory
   called MARX to keep the files better organized. However, this is not
   necessary. Copy all the disks that come with MarxMenu into a directory
   on your hard disk or network.

   If you do put the menu system in a subdirectory, it must be path
   accessible. That is, you must have a path statement in your autoexec.bat
   file that includes the directory where the menu system resides. A
   typical path statement might look like this:

    PATH=C:\;C:\DOS;C:\MARX;

   Copy all your Computer Tyme disks to the hard disk or network and type
   MARXINST. When it gets done, you can run some of the sample menus by
   typing MARX <menu>.

   -------------------- V E R Y * I M P O R T A N T ----------------------

   MarxMenu requires up to 100 bytes of free environment space. It won't
   run properly without it. The way you get more environment space is to
   add a SHELL command to your CONFIG.SYS file.

    SHELL=COMMAND.COM /P /E:nnn

   Where NNN is the number of bytes for the environment to reserve. Note
   that if you are running DOS that is earlier than 3.3 then NNN is the
   number of 16 byte blocks to allocate for the environment.

   For DOS 3.3 or later:

    SHELL=COMMAND.COM /P /E:400

   For DOS earlier than 3.3:

    SHELL=COMMAND.COM /P /E:25

   If MarxMenu gives you an environment space error, this is where you go
   to fix it.

   _______________________________________________________________


   THE MARX.BAT FILE   THE MARX.BAT FILE   THE MARX.BAT FILE

   In order for MarxMenu to work, a MARX.BAT file must be created. This is
   done by typing MARXINST. The first thing that MARXINST does is unpack
   the compressed menu files and documentation files. Then it will bring up
   the installation menu.

   The MARX.BAT file looks like this:

    @ECHO OFF
    C:\MARX\MARXMENU.EXE %1 C:\MARX
    %MXCMD%
    %0 %1

   The first line of MARX.BAT turns the echo off. This may be changed to
   ECHO ON for debugging purposes. PAUSE commands can be inserted to debug
   a menu. This allows you to see what's going on.

   The second line of MARX.BAT runs MARXMENU.EXE. The second parameter %1
   is the name of the menu file to run. The third parameter C:\MARX tells
   MarxMenu to use the C:\MARX directory for creating temporary batch
   files. This can be changed to any other directory you prefer.

   When the user selects a program to run, MarxMenu writes a temporary
   batch file which contains within it the commands to run the program.
   Then MarxMenu writes a command to the environment variable MXCMD to
   execute the temporary batch file and exits.

   What it writes depends on the version of DOS you are running. If you are
   running DOS 3.3 or later, MXCMD is set to CALL <batch>. If you are
   running an earlier version of DOS then MXCMD is set to COMMAND /C
   <batch>.

   Whatever command is written to MXCMD is executed in line 3. This usually
   calls the temporary batch file that MarxMenu created. This executes your
   program and returns to MARX.BAT.

   Line four jumps back to the beginning of the batch file and starts all
   over. %0 is MARX.BAT and %1 is the name of the menu you are running.

            MARX.BAT

   Computer Tyme MarxMenu Users Manual                     Page 9
   _______________________________________________________________


   Note: MarxMenu sets MXCMD = CALL $MX00000.BAT

   When you exit the menu system. MarxMenu sets MXCMD to MXSTOP. This jumps
   to a batch file called MXSTOP which gets you out of MARX.BAT. MXSTOP.BAT
   can be modified to control what happens when MarxMenu is exited.

   The default MXSTOP.BAT file is as follows.

    SET MXCMD=
    SET KSV=
    REM You can control menu exiting with this file!

   Note that by adding your own commands to MXSTOP that you can control
   what happens when you exit. You could loop right back to the menu if you
   want. Or, you could force a controlled network logoff.

   I strongly recommend upgrading to DOS 3.3 or later whenever it is
   possible to do so.

   The name of the temporary batch file is as follows:

                     $MX00000.BAT
                         ||||
           Shells--------+|++--------Network Station (Hex)
                     Task Number

   The 5 zeros are used for single user versions of MarxMenu. On a network
   they change as follows:

   The last 2 zeros is the station number on the network. This is either
   read directly from the shell, if you are using Novell, or from the
   environment variable STATION if you are on another network. The third
   zero is the task number if you are running DesqView, or from an
   environment variable TASK if you are running some other multitasker.

   The second zero is replaced by one less than the number of COMMAND.COM
   shells you are running. This way if you run COMMAND.COM under MarxMenu
   and then run MarxMenu again under that, it doesn't get lost when you
   exit.

   The first zero is for future expansion. In case something comes along
   that I haven't thought of.

   If you want to do custom tricks, MarxMenu has an internal variable
   called MxCmd. Setting this to your own command overrides the way
   MarxMenu would normally use it.



   Computer Tyme MarxMenu Users Manual                     Page 10
   _______________________________________________________________


   But now you ask, does MarxMenu leave a trail of batch files that will
   clutter up my drive or network? Not at all. MarxMenu keeps using the
   same names over and over again. If a user crashed his system, it might
   leave a batch file but it would be overwritten the next time he used the
   menu. Not only that, all batch files can be kept in the same directory
   so cleaning up is as simple as typing DEL $MX*.BAT!

   By writing to the MxCmd variable you can run an EXE or COM file directly
   without having to create another batch file.

    Example:
       OnKey 'M'
          |MxCmd = 'RAMMAP'

   This runs RamMap directly from the MARX.BAT file.

   Another trick is to run another batch file without the CALL statement.
   This creates a one way jump to another batch file.

   Another debugging feature. You can change the first line of the MARX.BAT
   file as follows:

    @ECHO %MXECHO%

   This allows you to turn the echo on for debugging purposes by typing:

    SET MXECHO=ON

   This way you don't have to change the MARX.BAT file to debug. If you use
   this, make sure that MXECHO is set to either ON or OFF.

   DROPTO.BAT   DROPTO.BAT   DROPTO.BAT

   If you are going to run a shell like COMMAND.COM under MarxMenu it is
   sometimes better to use DROPTO.BAT which is created during the install
   process. DropTo allows you to jump from the temporary batch file that
   MarxMenu creates to DropTo, which deletes the temporary batch file and
   executes the rest of the command line.

    Usage: DROPTO %0 COMMAND.COM

   If you are using DropTo inside a MarxMenu, the %0 is automatically added
   for you.

    Example:
       OnKey 'C'
          DropTo COMMAND.COM

   _______________________________________________________________


    DROPTO.BAT
    ----------
    DEL %1
    SET KSV=
    SET MXCMD=
    %2 %3 %4 %5 %6 %7 %8 %9

   Here's how it works:

        $MX00000.BAT <------deletes this file--------+
        ------------                                 |
        DROPTO %0 COMMAND.COM ------------> DEL %1 >-+
                                            SET KSV=
                                            SET MXCMD=
                 %2 executes COMMAND.COM--> %2 %3 %4 %5 %6 %7 %8 %9

   The advantages are that the temporary batch file is eliminated so if the
   user never returns to the menu, it leaves no temporary file to clutter
   up the drive. Also, DROPTO.BAT becomes the pending batch file that is
   running rather than the temporary file.

   SUPPORT FOR EARLY DOS VERSIONS   SUPPORT FOR EARLY DOS VERSIONS   SUPPORT FOR EARLY DOS VERSIONS

   There are two main differences between DOS versions earlier than 3.3 and
   versions 3.3 and above. One is the CALL command for batch files and the
   other is the way you specify environment space when using COMMAND.COM.

   I have enhanced the support for early DOS versions (3.0, 3.1, 3.2).
   MarxMenu executes COMMAND /C /E:nn (batchfile) >NUL to have one batch
   file call another. The first two lines of the batch files created are as
   follows:

    ECHO OFF
    CTTY CON
    ....

   This eliminates the ECHO OFF from being seen.

   Also whenever possible, when MarxMenu loads up a copy of COMMAND.COM, it
   adds the /E:nnn command to set the environment space to the same as that
   of the Master Environment. In versions earlier then 3.3 it is translated
   to paragraphs instead of bytes.

   One thing to note in early versions of DOS. If you run a batch file
   under COMMAND /C and your batch file has SET commands to set environment
   variables, the changes you make will disappear as soon as you get back
   to MARX.BAT. Why? Because you loaded another COMMAND.COM and the SET
   commands set its environment. When this COMMAND.COM ends, it takes its
   environment with it. Under DOS 3.3 or later, which uses CALL instead of
   another shell, the SET commands live. (Yet another reason to upgrade).

   ABOUT ENVIRONMENT VARIABLES   ABOUT ENVIRONMENT VARIABLES   ABOUT ENVIRONMENT VARIABLES

   I've been talking a lot about environment variables. Some of you out
   there in novice land don't know what an environment variable is. Many
   others don't know the intricate secrets handed down from the Great DOS
   Masters who know all the intricate undocumented features of DOS.

   Your DOS shell, COMMAND.COM owns an area of memory called the Master
   Environment. It contains strings in the form Name=Value. Included among
   those strings are your COMSPEC and your PATH. Your COMSPEC tells DOS and
   other programs where to find COMMAND.COM. Your PATH tells DOS and other
   programs what directories to search when loading programs. Another
   common environment variable is your PROMPT. This controls what your DOS
   prompt will look like.

   Environment variables are commonly set using the SET command. This is
   done by typing SET NAME=VALUE.

    Example:
       SET COLOR=BLUE

   So what does this actually do? Actually nothing, unless you have a
   program that reads the environment variables that is looking for one
   called COLOR. This way, environment variables can be used to leave
   messages to other programs and control how they behave.

   Besides leaving messages, environment variables can be accessed by batch
   files. If you use %NAME% in a batch file, DOS will substitute the VALUE
   of the variable for the %NAME% expression. And this feature is important
   to MarxMenu's operation.

   MarxMenu uses an environment variable called MXCMD. In the MARX.BAT file
   the third line is %MXCMD%. So MarxMenu controls MARX.BAT by writing
   values to MXCMD.

   In order to do this, there must be enough room in the environment for
   the command to fit. That is why you need to make sure that you have a
   SHELL command in your CONFIG.SYS to set space for MarxMenu to use.

   Now so far I've only talked about the Master Environment. That's the one
   that the first COMMAND.COM owns. Each program that is loaded, including
   TSRs, gets a copy of the Master Environment in its own environment. This
   is called the CURRENT Environment.

   One interesting feature of the Current Environment is that it is smaller
   than the Master Environment. DOS only creates enough space to hold a
   copy of the space used in the Master Environment and a little more to
   store the name of the program that is running.



   Computer Tyme MarxMenu Users Manual                     Page 13
   _______________________________________________________________


   If one program executes another program, the environment of the parent
   program is called the Parent Environment. You will probable never need
   to deal with the Parent Environment but MarxMenu can access it in case
   you do.

   Another environment is the SHELL ENVIRONMENT. This is the one that THEY
   never talk about. The one you'll never read about in any books. The one
   you'll never learn about in any DOS classes. This is the one your
   parents never mentioned.

   The Shell Environment is normally the same as the Master Environment.
   But, if you are running more that one level of COMMAND.COM, the Shell
   Environment is the environment of the last COMMAND.COM in memory. This
   environment is the most important environment to MarxMenu.

   So why load up two or more COMMAND.COMs? There are several cases where
   this could occur. One case is when you want to run COMMAND.COM as a
   program under MarxMenu. This way you can type EXIT to get back to the
   menu. If you do this and then run MarxMenu again, you have two levels of
   COMMAND.COM. In this case, the first COMMAND.COM is the Master
   Environment and the second COMMAND.COM is the Shell Environment.

   Another place where more than one COMMAND.COM is used is if you are
   running Microsoft Windows 3 or DesqView. Both of these programs are able
   to run a DOS shell. When you do, this is a second level of COMMAND.COM.

   What is important is that SET commands and %NAME% commands in batch
   files deal only with the Shell Environment and not the Master
   Environment.

   DEALING WITH MULTIPLE DOS SHELLS   DEALING WITH MULTIPLE DOS SHELLS   DEALING WITH MULTIPLE DOS SHELLS

   If you are running more than one level of COMMAND.COM (Shelling from
   Windows, DesqView, Word Perfect Office) and having environment space
   problems here's a trick. Before you load up your fancy shells, put this
   in a batch file like your AUTOEXEC.BAT.

   SET MXCMD=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

   This variable will be trashed by MarxMenu thus freeing up the
   environment space it occupied. This will not only allow MarxMenu to run
   but may solve problems with other programs you are running that need
   environment space as well.

   MARXMENU AND TSR CONTROL   MARXMENU AND TSR CONTROL   MARXMENU AND TSR CONTROL

   MarxMenu along with the TSR utilities that come with MarxMenu, can load
   and unload TSRs under menu control. This is handy when you want to run a
   big application and need to free up some memory to do it. Since MarxMenu
   is a 0k menu system, unloading TSRs is possible but it has it's tricks.

   The problem you run into is that when one batch file calls another batch
   file, the way MarxMenu normally runs, DOS creates a small batch file
   control block in memory. This control block stays in memory after the
   TSR is released creating a region of trapped memory. Although this
   memory is freed, it isn't usable.

   The way around it is to jump to the batch file that releases memory
   instead of calling it. This is done by setting MXCMD to the name of the
   batch file you want to run. The only problem is that when you jump to
   the other batch file, it won't automatically return to MARX.BAT. You
   must therefore end your batch file with a command bringing you back to
   MARX.BAT.

    MEMHOG.BAT
    -----------
    Rem UnLoad SideKick
    RELEASE SK
    CD\MEMHOG
    MEMHOG
    MARK SK
    SK
    MARX MAIN

   In your MAIN menu:

    OnKey 'H'
       |MxCmd = MEMHOG

   See the documentation file on the TSR utilities disk for more
   information on how to use MARK and RELEASE.

   NETWORK USERS:   NETWORK USERS:   NETWORK USERS:

   The main thing you have to worry about on a network is to make sure that
   when MarxMenu creates a temporary batch file, that it is a different one
   for each user on the network.

   This is handled several ways. If you are on a Novell network, MarxMenu
   uses your station number as part of the name for the temporary batch
   file. If you are not using Novell, then you will need to set an
   environment variable STATION for each workstation on your net. Each one
   has to be a different number.



   Computer Tyme MarxMenu Users Manual                     Page 15
   _______________________________________________________________


    Example:
       SET STATION=5

   You must ensure that the user has enough access rights to create
   temporary batch files in the directory selected for temporary batch
   files. One solution is to create a batch file directory and give all the
   users full access rights to it.

   MarxMenu has been run on about every DOS based network that exists. If
   the network runs at all it will generally run MarxMenu. Among the
   networks that come to mind are Novell, Lantastic, Banyan, 3COM, Lan
   Manager, IBM, DECNET, ConCurrent DOS, and SCO VPIX. MarxMenu is running
   on networks as small as two users to as large as 20,000 users. In fact,
   the bigger your network, the more you need MarxMenu.

   NOVELL USERS:   NOVELL USERS:   NOVELL USERS:

   Novell is the most popular network on the market. We have added many
   enhancements for Novell networks to support things like logging in and
   logging out, drive mapping, group support, software metering, and status
   information.

   Although Novell is a high quality solid product it has its own
   "Personality" and many undocumented features otherwise known as bugs.
   Most people who are having trouble with MarxMenu under Novell are really
   having trouble with Novell. Quite frankly, we do more Novell support
   than we do MarxMenu support.

   Having said that, I own two Novell networks. One at the lab and one at
   home and I love my networks. But, I have spent hundreds of hours
   learning all the tricks. And to save you a phone call, and me a lot of
   time, I've decided to share these tricks here in my manual.

   Some of these tricks are from the Great Network Gurus themselves who are
   so advanced that they no longer exist in physical form. These people
   live in another dimension of total mental existence and can only be
   reached my modem. Some of them hang out on Compuserve.

   I therefore strongly recommend that if you are a serious Novell user
   that you join Compuserve and hang out in the Novell section. And just
   because not everyone on Compuserve is a real person doesn't mean that
   you should feel uncomfortable asking them any question about your
   network that you need to ask.

   THE NOVELL MENU TRANSLATOR   THE NOVELL MENU TRANSLATOR   THE NOVELL MENU TRANSLATOR

   One nice bonus with Novell networks is that MarxMenu can translate your
   Novell menus to MarxMenu. This saves you the time of having to recode
   your system. What you do is type:

    MARXMENU NOVTRANS <menu>

   This translates your Novell MNU file to a MarxMenu MRX file. Your MNU
   file is unchanged. MarxMenu creates a TMP file containing the source
   code for the MRX file. Once you are satisfied with the MarxMenu file,
   you just delete the MNU file and rename the TMP file to MNU and forget
   that you ever had a Novell menu.

   Once the menu is translated you run it by typing MARX <menu> instead of
   MENU <menu>. MarxMenu can run Novell's menu better than Novell runs
   their own.

   LOGGING OUT UNDER MENU CONTROL   LOGGING OUT UNDER MENU CONTROL   LOGGING OUT UNDER MENU CONTROL

   Logging out under menu control is one of the trickiest things to do. The
   problem is that as soon as LOGOUT executes, you no longer have access to
   the network. This means that if you are in a batch file, you are going
   to get a "Missing Batch File" error, unless the batch file is in the
   \LOGIN directory.

   Another problem with logging out is making sure that your COMSPEC is
   pointing to a COMMAND.COM that is either on the local drive or in the
   \LOGIN directory. Otherwise you will get a "Cannot load COMMAND.COM"
   error.

   Another problem that you need to deal with is that your PATH command
   needs to be changed so that it doesn't refer to mapped drives that are
   no longer accessable.

   What you need to do is create a batch file in the \LOGIN directory
   called OFF.BAT.

    Example: F:\LOGIN\OFF.BAT

    CD\LOGIN
    SET COMSPEC=C:\COMMAND.COM
    LOGOUT
    C:
    PATH=C:\DOS

   Another way to logout under MarxMenu is to stuff the LOGOUT command into
   the keyboard buffer and exit MarxMenu.



   Computer Tyme MarxMenu Users Manual                     Page 17
   _______________________________________________________________


    Example:
       OnKey ESC
         |StuffKBD 'LOGOUT' + CR
         |ExitMenu

   This is the cleanest way when possible.

   Another logout trick is to use the LOGOFF utility from the Computer Tyme
   Network Survival Kit. This program automatically fixes your PATH and
   COMSPEC after the logoff occurs.

   LOGGING IN WITH MARXMENU   LOGGING IN WITH MARXMENU   LOGGING IN WITH MARXMENU

   If there is any one thing that's trickier than logging out of a Novell
   network, is logging in. I have spent MANY hours struggling with Novell
   trying to get it right and I have finally figured it out. Much of this
   comes from the Novell gurus who hang out on Compuserve and know
   everything there is to know about Novell.

   The first thing you need to do is make up your mind that you are going
   to do it right. The technique here might seem somewhat cumbersome, but
   it works well and will keep you out of trouble.

   MarxMenu has the ability to log you into a network, map your drives, and
   set your environment strings without having to touch a Novell utility to
   do so. MarxMenu can completely eliminate the need for Novell login
   scripts. The advantage to using MarxMenu in the login is that you have
   the power of 500 commands to work with instead of just 25 or so.

   THE CONFIG.SYS FILE   THE CONFIG.SYS FILE   THE CONFIG.SYS FILE

   The place to start is the place where DOS start when DOS boots. You MUST
   create a CONFIG.SYS file on your boot disk. The CONFIG.SYS tells DOS how
   many files and buffers to create, what device drivers to load, and the
   size of the Master Environment.

   Unless you are using special drivers, BUFFERS=40 and FILES=40 is a good
   place to start. STACKS 0,0 will gain you an extra 3k of ram. But the
   most important command is the shell statement. A CONFIG.SYS file might
   look like this:

    SHELL=COMMAND.COM /P /E:400
    BUFFERS=40
    FILES=40
    DEVICE=ANSI.SYS

   This sets up enough environment space to allow MarxMenu and DOS SET
   commands to work properly. You will also want to load any other device
   drivers like QEMM386.SYS or 386MAX.SYS to take advantage of other
   features of your computer. If you don't know about CONFIG.SYS files,
   read the DOS manual.



   Computer Tyme MarxMenu Users Manual                     Page 18
   _______________________________________________________________


   THE AUTOEXEC.BAT FILE   THE AUTOEXEC.BAT FILE   THE AUTOEXEC.BAT FILE

   After the CONFIG.SYS is loaded the AUTOEXEC.BAT runs next. Here you load
   up your TSRs and network drivers. There are some important tricks to be
   used here as well.

   First of all, never load your network shell from your AUTOEXEC.BAT file.
   Always have it branch to another batch file called LOADNET to load the
   network shell. Use the autoexec.bat only to load special TSRs and the
   IPX. An autoexec.bat might look like this:

    @Echo Off
    Cls
    IPX
    SET NET=NET4.COM
    SET COMSPEC=X:COMMAND.COM
    LOADNET

   The two SET commands are very important. The first sets a variable
   called NET to NET4.COM. This will be used later in LOADNET.BAT. By using
   this variable, you can have users running many different versions of DOS
   and still use the same LOADNET.BAT file. You could also use a command
   SET NET=LOADHI EMSNET4.EXE to take advantage of advanced memory manager
   software.

   Another trick is to run BESTNET from the Network Survival Kit. BestNet
   will automatically pick the best network shell and set the NET
   environment variable for you. You would use the command BESTNET instead
   of SET NET=NET4.COM in the AUTOEXEC.BAT file.

   The SET COMSPEC=X:COMMAND.COM is important if you are booting off of
   either a floppy drive or a diskless workstation. This assumes that X:
   will eventually be mapped to a directory on the network that has a valid
   COMMAND.COM in it.

   It is important to set the comspec BEFORE loading your NET shell. This
   prevents a problem where Netware wants to go back to the boot disk even
   after you change the comspec. I don't know why this works but it does.
   Trust Me. If you are going to use COMMAND.COM on drive C:, ignore this
   paragraph.

   Now we go to the LOADNET.BAT file.

    @Echo Off
    %NET%
    SET NET=
    F:
    STARTUP



   Computer Tyme MarxMenu Users Manual                     Page 19
   _______________________________________________________________


   The big concept behind LOADNET is that this file is NEVER CHANGED. You
   put in on all your workstations and in the LOGIN directory and it is
   EXACTLY THE SAME for every computer in your network. Any changes to
   individual computers are made in the AUTOEXEC.BAT file.

   So why is this important. Because if you are running diskless
   workstations what happens is that while you are booting you have a
   mythical drive A:. As soon as your NET shell loads this drive
   dissappears out from under you and you end up in F:\LOGIN. If you are
   running LOADNET.BAT when this happens you drop out of A:LOADNET.BAT and
   land in the middle of F:\LOADNET.BAT. And if your LOADNET.BAT is exactly
   the same file as the LOADNET.BAT in the \LOGIN directory, you take off
   running like the transition never occured.

   Even if you are not running on diskless workstations now, you might go
   to it someday. It also creates good programming habits and helps you
   boot up cleanly.

   Lets see what LOADNET does. The first line is @ECHO OFF, that's easy.
   The second line %NET% executes the network shell that you specified with
   the SET NET=NET4 command. This actually loads the network shell. The
   third line clears the NET variable freeing up space for other
   environment variables. F: switches you to drive F if you aren't there
   already. And finally STARTUP is the name of yet another batch file you
   jump to.

   The STARTUP.BAT file controls what happens AFTER LOADNET runs. This file
   can be freely changed so that LOADNET.BAT can stay the same. This lets
   you modify what happens AFTER the network shell is loaded.

   If you are using Novell's login program STARTUP.BAT might look like
   this:

    @Echo Off
    LOGIN

   USING A MENU FILE TO LOG IN   USING A MENU FILE TO LOG IN   USING A MENU FILE TO LOG IN

   If you are going to use MarxMenu to log in instead of Novell's
   utilities, you will want to print out the sample file LOGIN.MNU on your
   MarxMenu disk and study it. Your STARTUP.BAT file might look like this:

    @Echo Off
    SET BOOTUP=LOGIN
    MarxMenu Login
    %BOOTUP%

   If MarxMenu works correctly, it will change the environment variable
   %BOOTUP% to point to a file that it creates. If for some reason it fails
   (you make a mistake in the login), it will execute Novell's login and
   let you get in and fix it.



   Computer Tyme MarxMenu Users Manual                     Page 20
   _______________________________________________________________


   One word of caution. After modifing this menu, always run MARXCOMP LOGIN
   to compile it. Otherwise, if you boot up into it you won't have enough
   access rights to recompile automatically.

   NOVELL SEMAPHORES   NOVELL SEMAPHORES   NOVELL SEMAPHORES

   For a detailed explanation of Novell Semaphores, read the Novell
   manuals. What I've done is to export these functions to MarxMenu. I have
   implemented them slightly different than Novell did and have hidden all
   the nasties from you such as semaphore handles. All semaphores are
   accessed by name only.

   Here's a brief overview of semaphores. Semaphores are names of shared
   resources that the server keeps track of. Semaphores have three
   properties. They have a name, value and number of users. The name can be
   anything up to 48 characters long. The value is a number from -128 to
   127. If the value is less than 0, the resource the semaphore represents
   is considered used up.

   By opening a semaphore, you increase the number of users by one. By
   closing it, you decrease the number by one. If a single user opens a
   semaphore many times, it is only counted as one. When you log out, your
   semaphores are closed. This is also true if you turn your computer off,
   but it takes 15 minutes for the server to give up on you.

   The first user to open a semaphore creates it. The last user to close a
   semaphore deletes it. When a semaphore is created, a value can be
   assigned. If a semaphore is opened that already exists, the initial
   value is ignored.

   When NovWaitOnSemaphore is called by any user, the value is decremented.
   If the value is not below zero, NovWaitOnSemaphore returns true.
   Otherwise it returns false and the value is unchanged. The amount of
   time that NovWaitOnSemaphore will wait is controlled by the variable
   NovSemaphoreTimeOut.

   When NovSignalSemaphore is called by any user, the value is incremented.
   This allows other users to call NovWaitOnSemaphore and get a True value.

   NovSemaphoreUsers and NovSemaphoreValue are used to read the status of a
   semaphore without changing it's value.

   One of the major differences between how MarxMenu uses semaphores and
   the way Novell uses them is that normally a semaphore dies when the
   application finishes. This would normally prevent a 0k menu system from
   being able to use them. MarxMenu uses an interesting trick where it
   fools Netware into thinking that the semaphore belongs to another task.
   This allows the semaphore to live.



   Computer Tyme MarxMenu Users Manual                     Page 21
   _______________________________________________________________


   Semaphores can be tracked using FCONSOLE. Some versions of Netware have
   a bug in FCONSOLE that reports an open count that is 256 times the real
   count. Just divide by 256 for the right number.

   Semaphores can be used for software metering. This allows MarxMenu to be
   aware of what other users on the network are doing. Here are the basic
   tools, what you do with them is only limited by your imagination.

   RUNNING A MARXMENU   RUNNING A MARXMENU   RUNNING A MARXMENU

   MarxMenus are run by typing MARX and the name of a menu file such as
   SAMPLE.MNU. As discussed earlier, the menu file is a text file created
   with a text editor such as TEDIT.

    Usage: MARX <Menu Filename>

    Example:
       MARX SAMPLE

   In the above example, if SAMPLE.MRX doesn't exist, or is older than
   SAMPLE.MNU then MarxMenu will automatically load the complier,
   MARXCOMP.EXE to create a new SAMPLE.MRX file.

   In the never ending quest for more speed, MarxMenu is somewhat faster to
   load if you include the MRX extension.

    Example:
       MARX SAMPLE2.MRX

   By specifying the MRX extension, no test is made to compare the file
   date with the source file. Thus if you have changed the MNU file, you
   will still be running the old version. In order to force a recompile,
   type MARXCOMP SAMPLE.

   CUSTOMIZING MARXMENU SAMPLE FILES   CUSTOMIZING MARXMENU SAMPLE FILES   CUSTOMIZING MARXMENU SAMPLE FILES

   Included in the MarxMenu package are menu files which you can easily
   modify to execute your programs and perform other functions you desire.
   Using TEdit, the text editor included in this package, you can modify
   and customize these menu files.

   Also included to demonstrate the power and versatility of the menu
   system is a menu labeled NIM.MNU. This is a game written in the menu
   system that demonstrates some of the logic functions and programmability
   of the system. Use it for reference.



   Computer Tyme MarxMenu Users Manual                     Page 22
   _______________________________________________________________


    Here's a simple example of a menu file:
    ===================================
    ClearScreen
    DrawBox 30 9 25 8
    Writeln ' 1) Lotus'
    Writeln ' 2) dBase'
    Writeln ' 3) Wordstar'
    Writeln
    Write 'Select: '

    OnKey '1'
       cd\lotus
       123

    OnKey '2'
       cd\db3
       db3

    OnKey '3'
       cd\wordstar
       ws

    ====================================

   Notice in looking at the "OnKey" statements that all I have to do is
   tell MarxMenu how to get to the program. Although, MarxMenu takes care
   of reloading itself after exiting a selected program, its does not
   return to its own subdirectory as many other menu programs do.

   That means that if you execute a program in another subdirectory, when
   you come back to the menu, you remain in that subdirectory. If you
   normally run your applications with a batch file, consider having
   MarxMenu change directories and execute the program for you. This will
   eliminate debugging problems caused by the actions of your batch files.

   MENU ANALYSIS   MENU ANALYSIS   MENU ANALYSIS

   Let's start a simple analysis of the example menu file shown
   above. The ClearScreen statement simply clears the screen to
   give us a fresh workspace for the menu. DrawBox is the command to
   draw a box on the screen to contain some menu text. The Writeln
   command writes a line of text to the screen within the box, then
   positions the cursor on the next line. The menu text shows the
   available selection keys that the user has access to.

   ONKEY STATEMENTS   ONKEY STATEMENTS   ONKEY STATEMENTS

   The OnKey statements control what is actually executed. OnKey
   statements also allow you to execute hidden commands when you do
   not want them to appear on the menu screen. One trick I use is to
   have an OnKey statement define a key that runs TEDIT on my
   personal menu file. I don't show this key on the menu to keep
   others from poking around in the file. For additional security
   a password can also be set up on this key.

   Normally you enter a line of text as if you were creating a BAT
   file to run your application. Like batch files, if one of your
   commands is a batch file, all the statements after it will not
   execute. To prevent this you can use the CALL command to call a
   batch file in DOS 3.3 or later, or COMMAND /C in DOS 3.0, 3.1 and
   3.2.

   Normally, text displayed under an OnKey statement is the same
   text as the batch file created by MarxMenu. There are some
   exceptions. If a line starts with a "|" (vertical bar), the line
   will be interpreted by MarxMenu instead of being written to a
   batch file. This allows commands such as "PASSWORD" to be used.
   String variables can be passed as part of a batch command if the
   name of the string variable starts with a "%" symbol.

   The spaces preceding the commands under the OnKey statement are
   for clarity only. They are not necessary for MarxMenu to function
   properly.

   POPUP MENUS   POPUP MENUS   POPUP MENUS

   If you want to create a popup menu within a menu you can do so by
   using a "label". A label is a keyword preceded by a colon. To
   call the popup menu, place the keyword on a line by itself
   preceded by a carat (Shift 6). The label will precede the popup
   menu definition.

   For example if you have a popup menu to load Smart Software, you could
   name the PopUpMenu Smart. To bring up the Smart PopUpMenu, define a key
   in your main menu for Smart like this:

    OnKey 'S'
       ^Smart

   The Smart menu itself might look something like this:

    :Smart

    Writeln '  Data Base'
    Writeln '  Spread Sheet'

      |BoxInsideColor White Green
      |%1 = PickFile('C:\SMART\WORD\*.DOC',4,5,17)
      SM W -ALOAD %1

   While developing the menu, program one of the keys to run your favorite
   editor on the menu file that you are creating. This way, as soon as the
   change is made, the results will show when you exit your editor. Since
   MarxMenu allows versatility in creating the look of your menus, a little
   trial and error will be required to make things look right.

   THE CONSOLE   THE CONSOLE   THE CONSOLE

           +---| Console Functions |---+
           | 1 - Blank Screen          |
           | 2 - Set Blank Message     |
           | 3 - Lock Keyboard         |
           | 4 - Set Blank Time        |
           +---------------------------+

   The Console is a popup menu of built-in functions. To activate the
   console, press the TAB key. A menu will pop-up in the upper left hand
   corner of the screen. You can change the position of this popup menu
   with the ConsolePos function.



   Computer Tyme MarxMenu Users Manual                     Page 25
   _______________________________________________________________


   The first command on the Console screen is Blank Screen. Enter 1 and the
   screen will blank immediately. It will remain blanked until a key is
   pressed. Enter 2 on the Console menu and you can change the message
   displayed on the Blank Screen display.

   Enter 3 and you will be prompted for a word to lock the keyboard. After
   you enter the lock word the screen will blank and the keyboard will be
   locked until the exact lock word is typed. Enter 4 to set the number of
   minutes to wait before blanking the screen.

   The lock word feature is handy for times when you must leave the
   keyboard but don't want menu commands displayed for all to see. It also
   effectively locks the keyboard so someone can't escape to DOS and test
   the format command on your hard disk. We run this menu on a Novell
   Network and don't want to let everyone have access to the Supervisors'
   power at the touch of the escape key should we leave the keyboard.

   REPOSITIONING THE TOP WINDOW   REPOSITIONING THE TOP WINDOW   REPOSITIONING THE TOP WINDOW

   One nice feature you can use to get the windows right is to turn on the
   scroll lock. This lets you move the top window around the screen using
   the arrow keys so you can see how it looks. Then you can go into your
   menu code and set it permanently.

   Set Scroll Lock to "on". On most keyboards, a scroll lock LED will light
   up. Now use the arrow keys to move the top window to any position on the
   screen. Neat Huh?

   MOUSE SUPPORT   MOUSE SUPPORT   MOUSE SUPPORT

   If you have a standard mouse driver, MarxMenu will detect it and use it
   automatically. The left button on the mouse is the same as pressing
   return. The right button on the mouse is the same as pressing escape.
   Pressing both buttons on the mouse is the same as pressing the tab key.
   As of now, I'm not yet using the center button on the mouse for
   anything.

   The sensitivity of the mouse can be controlled using the MouseHorizontal
   and MouseVertical commands.

   STARTING OFF THE EASY WAY   STARTING OFF THE EASY WAY   STARTING OFF THE EASY WAY

   For those of you who want to just get a menu going and don't want
   anything complicated we have included a menu called the LEVEL1 menu.
   This menu is a fill in the blank type of menu that will get you going
   quickly and easilly.

   This menu requires no programming and explains itself. You run it by
   typing the command:

    MARX LEVEL1

   The first thing it does is scan your drive to find the directories. Then
   you just answer the questions and fill in the menu. This isn't as
   powerful as programming your own menu, but if you want something quick
   and dirty, this may be the answer for you.

   ABOUT VARIABLES   ABOUT VARIABLES   ABOUT VARIABLES

   One of the most unusual things about MarxMenu is its variables. MarxMenu
   handles variables differently than any other programming language. For
   the experienced programmer, this may require some adjustment since it's
   like getting used to driving a Cadillac after driving a VW Beetle.

   All variables in MarxMenu are like an empty box that can contain
   anything. A variable can be a number, boolean, string, file, array, etc.
   The type of variable is controlled internally and the user need not
   declare variable types.

   Variables are created with the VAR command:

    Var X Y Z

   If the word VAR is on a line by itself, the following lines, up to a
   blank line, are considered variable names.

    Var
      MyAge
      YourAge
      HisAge
      HerAge

   Variables are initialized to null values; 0 for Numbers, False for
   Booleans, and '' for strings. Initial values can be set when the
   variable is created.

    Var
      X = 6
      MyName = 'Marc'
      Programmer = True



   Computer Tyme MarxMenu Users Manual                     Page 27
   _______________________________________________________________


   Variables can change variable types. If you write a number to a string
   variable, the variable changes to a number.

    X = '234'
    X = Value(X)

   This is valid in MarxMenu. X now is a number and contains the value 234.

   Number variables are 32-bit integers ranging between plus or minus
   2,147,483,647.

   Boolean variables are True or False.

   String variables are limited to 255 characters.

   In MarxMenu, string literals are delimited by either single or double
   quotes.

    "This can't be yogurt!"
    'Lincoln said "Four score and seven years ago ..." '

   Numbers beginning with a '$' indicate base 16 or hex numbers.

   When choosing variable names, it is good programming practice to choose
   long meaningful names. This allows yourself and others to be able to
   read menus and follow the logic more easily.

   REAL NUMBERS   REAL NUMBERS   REAL NUMBERS

   So what's the difference between ordinary numbers and real numbers?
   Ordinary numbers in MarxMenu are 32 bit integers. These are numbers
   whose range is about plus or minus two billion. Integers are whole
   numbers and do not include any fractions.

   This is why MarxMenu has included REAL numbers (also known as Floating
   Point numbers). Real numbers in MarxMenu use BCD (Binary Coded Decimal)
   with 18 digits of accuracy. They have a range of 10 to the plus or minus
   63rd power, which means up to 63 zeros either side of the decimal point.
   This lets you work with very big and very small numbers.  MarxMenu has
   smart rounding algorithms so that 1.0 / 3 * 3 = 1.0 and not
   0.999999999999999999 like in most languages.

   Real numbers are specified by using a decimal point. Thus 5.0 specifies
   a real number. Most normal MarxMenu functions still require the standard
   32 bit integers. If you get the error: 'REAL found where INTEGER
   expected.' You need to use an integer.

   If an integer is passed where a real is expected, the integer is
   automatically converted to a real. Thus:

    6.0 * 3 = 18.0



   Computer Tyme MarxMenu Users Manual                     Page 28
   _______________________________________________________________


   The Value function returns real numbers if a decimal point is used in
   the string. All the relevant math functions will work with reals as well
   as comparison operators.

   MarxMenu supports a variety of functions for real numbers. It has trig
   functions, log functions, and exponential functions. So why do you need
   real numbers in a menu program? I don't know. I had a library and
   threw them in. I figure someone will need them someday.

   With real numbers you can do trigonometry calculations like those
   discovered by the ancient Indian chief Pythagoras who discovered what is
   now know as Pythagoras's triangle.

   Now I know that a lot of you were taught in Math class that Pythagoras
   was Greek. Well, it's just not so. Let me tell you the real story:

   Pythagoras was an Indian chief that had three wives. Two of the wives
   were twins and weighed 120 pounds each. And they sat next to Pythagoras
   on a pair of twin deer hides.

   But Pythagoras also had a third wife who was a large fat woman who sat
   across from Pythagoras on a hypopotamus hide. This wife weighed 240
   pounds.

   What Pythagoras discovered was that the squaw on the hypopotamus was
   equal to the sum of the squaws on the other two hides!

   LOCAL VARIABLES   LOCAL VARIABLES   LOCAL VARIABLES

   MarxMenu also supports local variables. Variables declared within
   procedures become local variables. Local variables are just like global
   variables in that you can use them as multidimensional arrays. When the
   procedure finishes, all local variables are disposed.

   If a local variable has the same name as a global variable, the local
   variable will be used.

   PASSING PARAMETERS TO PROCEDURES   PASSING PARAMETERS TO PROCEDURES   PASSING PARAMETERS TO PROCEDURES

   Procedures can accept parameters by declaring variable names on the same
   line as the name of the procedure.

   Procedures can return variables by using the Return command. Return
   exits the procedure returning the parameters on the same line as the
   Return statement.

    Example:



   Computer Tyme MarxMenu Users Manual                     Page 29
   _______________________________________________________________


    Procedure Factorial (X)
    var Y Z
       Y = 1
       Z = 1
       while Y <= X
          Z = Y * Z
          Y = Y + 1
       endwhile
       Writeln X ' factorial is ' Z
    endproc

   In this example, if you were to use Factorial (5) you would get:

    5 factorial is 120

    Another Example:

    Procedure AskYesNo (Question)
    var YesNo
       DrawBox (34 - (Length(Question) / 2)) 21 Length(Question) + 14 3
       TextColor LCyan Blue
       UseArrows Off
       Write ' ',Question,' (Y/N) '
       YesNo = UpperCase(ReadKey)
       YesNo = YesNo = 'Y'
       if YesNo
          Write 'Yes'
       else
          Write 'No'
       endif
       Wait 50
       EraseTopWindow
       Return (YesNo)
    EndProc

    if AskYesNo 'Do you want to continue? ' then Continue

   In this example, MarxMenu draws a box and asks a question and waits for
   a Yes or No answer.

   Arrays can be passed as parameters. Parameters are passed by value not
   by reference. This means that any changes to the passed parameter do not
   affect the original value.

   You can copy an array by assigning it equal to another array.

    Example:

    Array1 = Array2



   Computer Tyme MarxMenu Users Manual                     Page 30
   _______________________________________________________________


   This creates Array1 with a copy of all the elements of Array2. The
   previous contents of Array1 are overwritten.

   ABOUT CONSTANTS   ABOUT CONSTANTS   ABOUT CONSTANTS

   Constants are used to give values meaningful names. By using constants a
   value can be assigned once and the constant name used throughout the
   menu program. This way, if you change the value of the constant, all the
   places where that constant is used automatically change.

   This is good programming practice.

    Examples:

    Const States = 50 CPU = '80386 SX' WeekEnd = True

    or

    Const
       States = 50
       CPU = '80386 SX'
       WeekEnd = True

   Using the word STATES is just like using 50. Using CPU is just like
   using '80386 SX'. But if throughout my menu I use CPU, and then I get a
   new computer with a 80486, I can just change one line:

    Const CPU = '80486'

   And all the places I used CPU changes to '80486'. This is the correct
   way to program.

   ABOUT ARRAYS   ABOUT ARRAYS   ABOUT ARRAYS

   MarxMenu supports multidimensional arrays up to 31 dimensions. Unlike
   other programming languages, arrays need not be declared. MarxMenu
   creates arrays "on the fly" and automatically takes care of the array
   size and number of dimensions.

   Another unusual feature of MarxMenu arrays is that they are an array of
   MarxMenu variables. This means that elements of MarxMenu arrays need not
   be of the same type. Element 1 can be a number, element 2 can be a
   string and element 3 can be another array.

   This type of variable management leads to the easy creation of very
   powerful data structures as you will see.

    Var X



   Computer Tyme MarxMenu Users Manual                     Page 31
   _______________________________________________________________


    X[1] = 'Element 1'
    X[2] = 3
    X[3] = True
    X[4,6] = 9
    X[4,7] = 'Ten'

   These are all valid statements. MarxMenu creates a two dimensional array
   here. If we now execute the following statement:

    X[4] = X[4,6] + X[2]

   X[4] becomes equal to 12 but variables X[4,6] and X[4,7] are lost. This
   is because we have changed an array into a number. MarxMenu
   automatically handles the deallocation of memory used by this array and
   its elements and returns the space the used to the memory pool.

   ABOUT QUALIFIERS   ABOUT QUALIFIERS   ABOUT QUALIFIERS

   Qualifiers are named indexes into arrays. They are used to make the
   source menu file more readable and more organized.

   Suppose we are creating a data structure to deal with places in the
   United States. First we will need an array for States.

    Var States

    We want to store some facts about the states.

    Qualifier
       Population
       Bird
       Motto
       County

    State[3].Population = 10000000
    State[3].Bird = 'Chicken'
    State[3].Motto = 'Best politicians money can buy!'

   Now states have counties and counties have county seats, sheriffs, and
   cities.

    Qualifer
       Sheriff
       Seat
       City

    State[3].County[7].Sheriff = 'Buck InBred'
    State[3].County[7].Seat = 'Possum Trot'

   Now counties have cities and cities have schools, mayors, churches, and
   taxes.



   Computer Tyme MarxMenu Users Manual                     Page 32
   _______________________________________________________________


    Qualifier
       Schools
       Mayor
       Churches
       Taxes

    State[3].County[7].City[9].Schools = 8
    State[3].County[7].City[9].Mayor = 'Virgil Collins'
    State[3].County[7].City[9].Churches = 120
    State[3].County[7].City[9].Taxes = '$100,000,000'

   The above line is the same as:

    State[3,4,7,3,9,4] = '$100,000,000'

   As you can see with qualifiers, it is easy to create multidimensional
   arrays in a way that is organized and readable.

   In this example, the qualifier Population became equal to 1. Bird became
   equal to 2. The variable references, State[3].Bird and State[3,2] are
   the same. It's just that one is more readable than the other. Qualifiers
   normally begin by assigning 1 to the first name and 2 to the second
   etc. This can be modified.

    Qualifier
       Color = 7
       Size
       Shape

   In this case Color becomes the number 7; Size becomes the number 8; and
   Shape becomes the number 9.

   COMMENTS IN MENU FILES   COMMENTS IN MENU FILES   COMMENTS IN MENU FILES

   MarxMenu has three ways to add comments to a menu file. The first way is
   with the Comment command.

    Comment
    ========================
    This is a comment block.
    ========================
    EndComment

   All lines up to EndComment are ignored.

   The second way is with a ';'. All text to the right of the ';'
   (semicolon) is ignored.

    BlankTime = 20  ;this is where we set the blank time.



   Computer Tyme MarxMenu Users Manual                     Page 33
   _______________________________________________________________


   The third way is using {} or curly braces. Anything inside the curly
   braces is ignored. Curly braces can be nested.

    {All of {this} is a comment.}

   Comments are ignored by the compiler and cost you nothing in execution
   speed. Comments can save you a lot of time if you have to come back
   later and work on your menu, or if someone else has to work on it.
   Therefore, I encourage you to use comments as much as possible.

   THE MARXMENU COMPILER   THE MARXMENU COMPILER   THE MARXMENU COMPILER

   MarxMenu reads your MNU files and creates MRX files. These MRX files are
   a highly digested form of the MNU file that you created. MRX files are
   the compiled files.

   When you run MarxMenu, the interpreter MARXMENU.EXE looks for the menu
   file with the MRX extension. If it doesn't find it, MARXMENU.EXE will
   automatically load MARXCOMP.EXE and compile the menu. MARXMENU.EXE also
   compares the file dates of the MNU and the MRX files. If the MNU file is
   newer than the MRX file, the complier will be loaded.

   MarxMenu will also force a compile if the MRX file was not complied by
   the same version and release date of the MarxMenu you are using. MRX
   files are not compatible from one version of MarxMenu to the next.

   You can also force a compile from the command line by typing MARXCOMP
   <menu>.

   COMPILER COMPATIBILITY   COMPILER COMPATIBILITY   COMPILER COMPATIBILITY

   The MarxMenu compiler is fully compatible with earlier versions of
   MarxMenu with a few exceptions. The new compiler does a lot more error
   checking than earlier versions of MarxMenu and will catch errors that
   you used to get away with. Other than that, the only difference you
   should notice will be a speed increase.

   Earlier versions of MarxMenu had separate names for variable types. The
   names $VAR, BVAR, #VAR, and FILEVAR act the same as typing VAR.

   Very early versions of MarxMenu had a different form of the USEARROWS
   command that required 4 to 5 numbers after it. If you run into this
   error, just get rid of the numbers after USEARROWS and it will work
   fine.

   A WORD ABOUT DOS VERSIONS .....   A WORD ABOUT DOS VERSIONS .....   A WORD ABOUT DOS VERSIONS .....

   Versions of DOS below 3.3 will cause MarxMenu to use 3.5k of ram where
   3.3 DOS and above use no memory. 3.2 DOS is very buggy and should be
   replaced. 3.1 DOS isn't too bad for bugs but if you're using the BACKUP
   and RESTORE programs that came with it, you're in trouble. They don't
   work on large files. You'll find that out if you try to restore one of
   them.

   MS-DOS 4.01 seems to be pretty clean provided you have the April-89
   release or later. To determine if you do, check the file date on
   COMMAND.COM. Earlier versions of DOS 4.01 have SERIOUS BUGS. If you are
   running any DOS 4 earlier than April-89 you should upgrade immediately.

   DR-DOS or EZ-DOS are pretty good also. It is very compatible as long as
   you don't get too strange with it. I recommend version 3.4 or later.
   4DOS is also pretty good but sometimes some of the advanced features in
   this product can cause it to behave differently than DOS. This requires
   extra care when writing your menus.

   MarxMenu should work correctly on 386 type multiuser operating systems
   such as Digital Research's Concurrent DOS 386 or SCO VPIX DOS emulators.
   Although MarxMenu should run under PC-MOS I do not recommend it. My
   experience with PC-MOS has been nothing but grief.

   MarxMenu will not run correctly under DesqView 2.26. It will run under
   2.25 or 3.21. So if you are running 2.26, it needs to be upgraded.
   MarxMenu contains several support functions for DesqView.

   If you are running under some weird DOS and are having problems, try it
   under "regular" DOS and see if it goes away. If it does, try to find out
   what it is about your weird DOS that makes it not work right. I am
   interested in being compatible with as many systems as I can. Let me
   know if you are having problems. But also, try to get your wierd DOS
   vendors to clean up their act.

   A WORD ABOUT BUGS .....   A WORD ABOUT BUGS .....   A WORD ABOUT BUGS .....

   Although I try to create perfect bug free software, every now and then
   even I make a mistak. If you find one, let me know and I'll fix it.

   TIPS FROM THE MASTER   TIPS FROM THE MASTER   TIPS FROM THE MASTER

   Since MarxMenu is a programing language, I want to talk about what
   programing is and how it is accomplished. I want to dispel some myths
   and fears relating to it and introduce you to techniques that will help
   you write code neatly, quickly, and efficiently. From the outside,
   programming looks like magic; but once you know a few of the tricks, its
   really not too hard.

   Many of us who were raised on 50s and 60s science fiction television
   learned that it is the brainy types who deal with computers. It almost
   gives you the impression that the computer is smart and you are dumb. As
   you use the computer, it is evaluating you, and if it figures out that
   its smarter than you, it can get your job and replace you.

   COMPUTERS DO SIMPLE TASKS   COMPUTERS DO SIMPLE TASKS   COMPUTERS DO SIMPLE TASKS

   A computer is a simple device. It does simple tasks. It just does them
   very fast and accurately. Computers don't even know basic things like
   how to write letters on the screen or how to read the keyboard. These
   are programs that the computer runs. Someone had to program your
   computer to do even the simplest of tasks.

   As you learn to use MarxMenu start with the simple menus. The SAMPLE.MNU
   is a very easy program. Study it and understand how it works. Make a
   copy of it and change one selection to run one of your programs.

   Once you have changed one selection, change several more. Now MarxMenu
   is running your programs, and you have made it work. Then try something
   new. Add more selections. Change the size and position of the box to fit
   your needs.

   Take the time to play with it. Try new commands. Build up your menu. Be
   artistic. The more you work with it, the more you will learn.

   COMPLEX TASKS ARE MADE OF SIMPLE TASKS   COMPLEX TASKS ARE MADE OF SIMPLE TASKS   COMPLEX TASKS ARE MADE OF SIMPLE TASKS

   As you learn more about MarxMenu, move on to SAMPLE2.MNU. Here we use
   more of the power of the MarxMenu language. As you study this menu, you
   will notice something. Even though it looks complex, it is really a
   collection of simple tasks. Understand how the moving windows work.
   Understand that the pop-up menus are just like the main menu. You will
   see that it is really not a complex menu at all. It is a lot of simple
   processes hooked together.

   That is one of the main concepts behind programming. Complex tasks are
   built out of simple tasks. As you learn the simple tasks, you will
   quickly understand how to connect them to accomplish complex tasks.

   When one sees a castle, one can't help but to be impressed. But castles
   are made of stones. And you can't build castles until you understand how
   stones work. Then you realize that a castle is just a bunch of stones
   hooked together. Programming is just like that.

   To successfully understand MarxMenu, start at the bottom and work your
   way up. Each little trick you learn becomes another building block for
   the next trick. What you start with becomes the foundation for the work
   that you will eventually produce.

   LEARNING GOOD PROGRAMMING HABITS   LEARNING GOOD PROGRAMMING HABITS   LEARNING GOOD PROGRAMMING HABITS

   Programming has its pitfalls, here I hope to give you some tips that
   will help you avoid common mistakes. This, I hope will give you a head
   start on the road to MarxMenu being done right.

   The first concept is patience. Rome wasn't built in a day. You may not
   be able to write grand and glorious menus the first try. In fact, you
   may have trouble getting the damn thing to work at all. As you have
   probably already noticed, no program is perfect. Sometimes there are
   errorrs in the manual. Sometimes it just doesn't work like you expected,
   or does not work the same way as other programs that are familiar to
   you.

   But, once you complete the installation, give it some time and realize
   that there is a lot of potential here. Approach all challenges with a
   good attitude.

   I learned computers the hard way. Out on the streets. Hanging around
   with other computer nerds in the late 70s who never went to college
   either. I was known as a Bit Wit. My first real computer was an IMSAI
   kit. Actually, it wasn't all IMSAI, it was a combination of several kits
   where no two boards came from the same supplier. It was in an IMSAI box,
   so I call it an IMSAI.

   It was all supposed to work together the salesman told me the day before
   they went out of business. And it all did after some redesigning. I was
   tired of fixing CB radios for a living and decided that computers were
   here to stay and that I was going to learn about them.

   With that in mind, everything that went wrong became an opportunity for
   growth. Not that I looked forward to things not working. I programmed
   the thing from scratch, loading binary codes into memory from an array
   of switches on the front panel.

   The first program I wrote ran the EPROM burner, which was the only
   storage device I had. After I saved this program on a chip, I used it to
   load the second program onto the chip.



   Computer Tyme MarxMenu Users Manual                     Page 37
   _______________________________________________________________


   Eventually I wrote enough software to talk to the screen and keyboard.
   Now I could type hex codes on the screen and save them to a chip.
   Eventually I wrote a tape driver and could save stuff on tape. Later, I
   traded for a North Star disk drive and had a disk system. One 90k
   floppy. I thought I was in heaven.

   I was intimately familiar with my computer. All my programs were in
   object code with no documentation whatsoever. At that point, a friend of
   mine, Rufus, turned me on to a language called FORTH.

   Being an interesting language and very powerful, I typed in the whole
   compiler in hex and adapted it to work on my system. Once I got Forth
   up, I wrote a line editor in it. I then used the line editor to write a
   screen editor. With the screen editor, I rewrote Forth in Forth. The
   language compiled itself.

   From working with Forth (which is as much a religion as a programming
   language) I learned both good and bad habits. Forth is a write only
   language and is almost impossible to read even with the best of
   documentation. On the other hand, it is as close to the machine as you
   can get in a high level language.

   After opening up a computer store in 1984, it became time to make the
   jump from CP/M to the DOS world. Turbo Pascal offered an interesting
   solution. They had both a CP/M and DOS compiler. This meant that
   programs I wrote would run on both machines. The thing that struck me
   about Pascal was that I could read it better than Forth, and I didn't
   even know the language. Not only that, but I could follow the programs
   that other people wrote and incorporate their code into my programs.

   The more programs I wrote, the more I came to appreciate a language that
   was reader friendly. I could manage my programs much easier without
   having to remember so much. Other people could follow what I was doing
   easier.

   The important thing I learned was that readability is very important in
   a program. The more complex the program, the more important readability
   becomes.

   One of the main design factors in the MarxMenu language is readability.
   I could have used short names for my commands and it's not like I like
   to type. I'm still on just two fingers here. Its just that descriptive
   names are so much more meaningful when putting simple processes together
   to create complex processes.

   The point (finally) is, when creating variable names, or procedure
   names, use long meaningful names. It may take more typing, but it takes
   a lot less thinking and remembering later on. Consider the following
   example in choosing variable names.



   Computer Tyme MarxMenu Users Manual                     Page 38
   _______________________________________________________________


    Var KlingonsDestroyedInBattle
    Var K

   In the above example, it is obvious which one tells you more about what
   information is stored in the variable.

   USE COMMENTS LIBERALLY   USE COMMENTS LIBERALLY   USE COMMENTS LIBERALLY

   Even though MarxMenu is easy to read, it still should be commented. The
   examples that come with this disk do not have as many comments as they
   should. Don't do as I do, do as I say. I'm lazy and a bad example.

   Comments are not compiled in your MRX files and cost you nothing at
   execution time. In order to make commenting easy, I have provided three
   separate comment commands. Learn these commands first.

   Every menu should include a title comment. This should include the name
   and phone number of the person who wrote it. If you have a problem with
   a menu and you send it to me, I expect a title comment. That way I can
   call you about it.

    This form of comment block is better than using ';' because not using ;
    allows you to turn your word wrap feature on and do some professional
    looking editing in the comment block. This kind of comment block should
    be at the beginning of each and every menu you create.

    The top and bottom bars are for looks only and are not necessary to the
    comment. I strongly encourage you to use bars and do things for looks
    in source code. Looks are very important and you should put as much
    care into your comments as you do in writing a business letter.

    If you learn MarxMenu well, your source code may be part of your next
    job interview as you move up the corporate ladder. So you want it to
    look good.

    By the way, if you upload your menus to my bulleten board, I expect a
    comment block at the top of your menu with your phone number so I can
    get back to you.

   INDENT YOUR CODE   INDENT YOUR CODE   INDENT YOUR CODE

   As programs get more complex, it gets harder to match the IFs with the
   ELSEs and the ENDIFs. This is where indenting comes in. It creates a
   logical grouping of statements and you can easily see what goes with
   what.

    Procedure IfDemo
       IF <condition>
          <statement>
          <statement>
       ELSE
          <statement>
          <statement>
          WHILE <condition>
             <statement>
             <statement>
          ENDWHILE
          <statement>
       ENDIF
       <statement>
    EndProc

   You can easily see how this helps you follow what you are writing. Now
   here's a new trick. If you are using an IF, and plan to use an ELSE and
   an ENDIF, on the line under the IF statement, type in your ELSE and
   ENDIF lines. Then go back and insert your statements in between these
   lines. This will help you avoid forgetting the ENDIF or getting mixed up
   as to which IF matches which ELSE.

   A similar trick can be done with parens and brackets. When typing a left
   paren, type the matching right paren with it. Then fill in the code you
   want to put inside the parens or brackets.

   FOR DUPLICATE TASKS, USE PROCEDURES   FOR DUPLICATE TASKS, USE PROCEDURES   FOR DUPLICATE TASKS, USE PROCEDURES

   As menus become longer and more complex, many times you are duplicating
   a process that you already have written. Although it is easy to copy a
   block of code, it is better to create a procedure.

   With procedures, the process is put in one place and is given a name.
   Preferably a long meaningful name. Once this procedure is defined and
   named, it can be used as if it were part of the MarxMenu language. This
   makes menus smaller and easier to read. It is also a way for you to
   combine small processes into large processes. Procedures can be built
   using other procedures.

   Once you have a process figured out and working in a procedure, the
   whole process becomes a black box with a name that you can use
   elsewhere. The whole process is reduced down to a name that just works!



   Computer Tyme MarxMenu Users Manual                     Page 40
   _______________________________________________________________


   Another advantage of procedures is that if circumstances change and the
   procedure needs to be modified, you only make a change one place in your
   menus, and everything that uses that procedure is automatically changed.
   This makes menu maintenance easier.

   DON'T PROGRAM YOURSELF INTO A CORNER   DON'T PROGRAM YOURSELF INTO A CORNER   DON'T PROGRAM YOURSELF INTO A CORNER

   Using the above techniques will allow you to write very complex menu
   systems. Failing to use these techniques can limit what you can
   accomplish. There is a term called "programming yourself into a corner"
   which refers to a program that is so poorly written, that it can't be
   modified to accommodate changes and improvements.

   The height of your programming abilities depends on the foundation on
   which they are built. You must avoid rushing to the top without first
   creating a firm foundation on which to build. Good technique is the
   foundation for good programming. You will have to learn it eventually,
   it is more efficient to do it right than it is to do it over.

   Adopting good programming habits reminds me of my favorite light bulb
   joke:

   Q. How many psychologists does it take to change a light bulb?

   A. Only one, but the light bulb has to want to change.

   A WORD TO WRITERS AND REVIEWERS   A WORD TO WRITERS AND REVIEWERS   A WORD TO WRITERS AND REVIEWERS

   MarxMenu is a multi-level product fulfilling the needs of a large
   variety of computer users. It is difficult to compare this product on a
   feature to feature basis. This is because MarxMenu has about 10 times as
   many features as any other menu system. These features allow this
   product to target a very broad variety of computer users, from the
   novice user, who will only use the LEVEL1 menu, to large companies with
   hundreds of file servers controlled through the MarxMenu language.

   One common mistake that writers make when evaluating MarxMenu, is in the
   area of ease of use. If you are looking for ease of use, stick with the
   simple menus and the self-configuring menus such as the LEVEL1 example.
   By looking at it this way, MarxMenu will be as easy to use as any other
   menus system out there and can be compared for similar features. Even
   though MarxMenu supports complex commands, it is not necessary to use
   them in simple menus.

   If you are doing a comparative review, please let me know on what basis
   you are making comparisons. This way I can assist you by providing you
   accurate information in the area of your interest. If you are looking
   for simple, I can show you simple; if you are looking for power, I can
   show you power.

   _______________________________________________________________


   On the other hand, if you are reviewing power tools and network
   utilities, you might want to look at the Network Survival Kit and not
   just MarxMenu. So if you have a copy of only this program, give me a
   call and I'll get you the latest and greatest.

   In addition to our software, we also have color prints and color slides
   available as well as product literature and sample reviews. These are
   available to make your job easier and help you make those deadlines.

   MarxMenu tends to be best reviewed as a long article rather than a short
   one. It is very good if you have a lot of space to fill. With a long
   article, you can get really in depth with what MarxMenu is able to do.

   Any publication which reviews any of my products gets a site license to
   that product whether I like the review or not. Our position is that if
   you are using MarxMenu yourself, you will get to know it better.

   So far, as of the date I write this, no writer has written an article
   about MarxMenu that I feel covered what this product is really capable
   of doing. Consider this a challenge.

   Any questions you have about any of my products, feel free to call. The
   main thing I ask is that you get the product name, price, our address,
   and our phone number right.

   USING MARXHELP   USING MARXHELP   USING MARXHELP

   MarxHelp is a TSR pop-up help program for MarxMenu. It acts as an online
   reference guide to all of the MarxMenu commands. MarxHelp only takes 8k
   of ram and is very useful while writing your MarxMenu applications.

   To load MarxHelp type MARXHELP at the command line. Then if you want to
   pop-up an index press Shift-F3. The Shift-F2 key will repeat your last
   help topic and Shift-F1 will look up the word your cursor is on.

   To get more help on MarxMenu type MarxHelp /?. If you need to unload
   MarxHelp from memory, type MarxHelp /U.

   MarxHelp comes with the Computer Tyme Network Survival Kit. It can also
   be downloaded from our support BBS. It does not come bundled with the
   single user version.

   PRINTING THE EXAMPLE FILES   PRINTING THE EXAMPLE FILES   PRINTING THE EXAMPLE FILES

   MarxMenu comes with several example programs from simple to complex. The
   first thing to do is print the sample menus and study them. Start with
   the easy ones. You may never need to use any of the more complex ones,
   but if you do, a large variety of advanced techniques are demonstrated.

   By studying the sample menus, and comparing them to this manual, it
   should be fairly easy to become productive writing your own menus.

   MARXMENU COMMANDS   MARXMENU COMMANDS   MARXMENU COMMANDS

   MarxMenu contains a rich set of commands. They are listed here
   alphabetically and by command category. You don't have to learn them all
   so don't let the size of the list scare you.

   In the following command list, words contained within ( ) are command
   parameters that must be included after the menu command. If the
   parameter is not required, it will be contained in [ ]. The numeric
   range for the <column> parameter is 1 - 80 decimal, and for the <row>
   parameter the range is 1 - 25, 43, or 50 decimal depending on how many
   lines your monitor displays.

   | (Vertical Bar)   | (Vertical Bar)   | (Vertical Bar)
   Forces MarxMenu interpretation under an OnKey Command. If not for the |
   (Vertical Bar), the command under an OnKey would be written to a batch
   file. The | is only used under OnKey commands.

    Example:
      OnKey 'S'
        |password 'hello' 3 4
        ECHO Type EXIT to return to menu
        COMMAND.COM

      OnKey 'X'
        |If UpperCase( ReadEnv( 'USERNAME' ) ) = 'SUPERVISOR'
          SYSCON
        |Else
        |  SecurityBreach( 'You do not have access to this function!' )

   Chain (MenuName)   Chain (MenuName)   Chain (MenuName)
   This command will load a new menu. Unlike Jump, MarxMenu stays in
   memory. The screen is not cleared. If the new menu has exactly the same
   global variables, the contents of all global variables is retained.
   Chain allows for a very quick transfer from one menu to another.

    Example:
      Chain ('USER')  ;Chains to USER.MNU

   ClosePrinter   ClosePrinter   ClosePrinter
   In MarxMenu the printer is just another text file. Closing the printer
   is not required for ordinary printing. If you are changing printers you
   need to run ClosePrinter before changing the printer name. The printer
   is automatically opened by MarxMenu any time you print anything.

   If you are running Windows or DesqView, closing the printer allows other
   programs to access the printer. So if you are running under any
   multitasking shell, be sure to close the printer when you are done with
   it.

   If you are using a network like Novell, ClosePrinter will end the print
   job and send it to the print queue. This avoids the need to wait for
   print capture timouts to take effect.

   Closing the printer is good programming practice and will help you stay
   out of trouble. It's like what your mother taught you. "When you're done
   with something, put it away."

   Deletes characters from string starting at pos for count.

    Example:

      Delete(String,2,3)

   This leaves a String containing 'ABFGH'

   If count exceeds the length of the string, the string is truncated at
   pos.

   Another use of Delete is to delete elements of an array.

   Delete (Array,Position,Count)
   This works exactly like the delete command for strings. It delete
   elements of an array beginning at Position for Count elements. The

   Execute (command string)   Execute (command string)   Execute (command string)
   This allows you to execute a program without dropping out of MarxMenu.
   MarxMenu remains resident in memory and takes up approximately 100k. No
   batch file will be created by MarxMenu.

   This is handy if you have a small program you want to run from the menu
   but don't want to allow for the time required by MarxMenu to create and
   run a batch file. You can also execute some programs in a MarxMenu
   window (See Also: DosWindow). You can also execute a program and examine
   the return code.

   This command can be placed in a progression of menu commands without any
   special handling. Under an OnKey statement, you will need to enclose the
   command between a begin and end statement.

    Example:
      OnKey 'D'
      |Execute 'C:\DM.COM'

   Note: If UseCommand is True or On, MarxMenu will load COMMAND.COM to
   execute your command. If UseCommand is False, MarxMenu will execute your
   file directly without COMMAND.COM. Using COMMAND.COM will execute
   slightly slower, use 3.5k more ram, and allow you to use command lines
   just like you would from the DOS prompt.

   COMMAND.COM is required when running internal DOS commands like COPY or
   DIR. It is also required to run batch files.

   When UseCommand is off, MarxMenu will search the PATH for the executable
   file.

   Not using COMMAND.COM allows you to use the ReturnCode variable to get
   the ERRORLEVEL from the subprogram.

   The ClearScreenFirst (On/Off) controls whether MarxMenu will clear the
   screen before you execute.

   The PauseAfterExecute (On/Off) allows you to have a pause like the Pause
   command in batch files. That way you can read the screen before it
   restores the MarxMenu screen.

   This is used to insert the menu code from another file into the menu

    Example:
      Include 'DOS.MNU'

   This will compile DOS.MNU into your present menu as if that whole file
   were part of the menu you are working on.

   This is useful if you have several menus that share common code. By
   moving this common code to a separate file, and using an Include
   statement, you can change the common code and update several menus at
   once.

   Changing an include file does not cause MarxMenu to recompile
   automatically like changing the MNU does. You will have to force it to
   compile your menus.

   Loop   Loop   Loop
   MarxMenu has a looping structure that lets you execute a piece of code a
   specific number of times. It is used as follows:

    Example:
      Loop 8
         Writeln 'Pass Number ' LoopIndex
      EndLoop

   You start with LOOP (Number) which specifies the number of times to
   execute the code between LOOP and ENDLOOP. There are 2 variables
   available here for loop control. LoopIndex starts at 1 and is
   incremented at each EndLoop. When LoopIndex becomes greater than
   LoopLimit, the loop exits. LoopIndex and LoopLimit refer to the
   innermost loop.

   As loops are nested LoopIndexes and LoopLimits are kept in two arrays;
   LoopIndexStack and LoopLimitStack. There is also a variable called
   LoopLevel which points to the current loop parameters.

    Thus:
      LoopIndex is the same as LoopIndexStack[LoopLevel]
      LoopLimit is the same as LoopLimitStack[LoopLevel]

   You may therefore access outer loop parameters through the loop stacks.
   For instance LoopIndexStack[LoopLevel - 1] would refer to the second
   innermost loop index. LoopIndexStack[1] refers to the outermost loop.



   Computer Tyme MarxMenu Users Manual                     Page 76

   The loop variables can be read and written to so you can adjust the
   looping parameters while inside the loop. You can even adjust the
   parameters of outer loops.

   OnKey (char)   OnKey (char)   OnKey (char)
   When char is selected, the line(s) following are executed up to the next
   OnKey or end of file. This means that they are written to a BATCH file.

    Example:
      Onkey 'W'
      cd\wordstar
      ws
      cd\menu

   In the above example if 'W' is selected, MarxMenu will create a
   temporary batch file containing all the lines under the OnKey command.
   All the lines under an OnKey are written literally to the batch file
   with few exceptions. All leading and trailing blanks are stripped.
   String variables are evaluated and their value passed if the name of the
   string variable starts with a '%'.

   If a line begins with a '|' (vertical bar), the line is interpreted
   rather than written to a batch file. If a '^Label' is used under an
   OnKey, a jump is made to the 'Label' and interpretation is resumed. This
   is commonly used to jump to a submenu.

   Any OnKey statement that causes a batch file to be written to will cause
   the menu to exit. MarxMenu normally will exit with ErrorLevel 0 unless
   an ExitCode is set.

   The first blank line under an OnKey ends what that OnKey command does.

   This command opens the printer device. It is not necessary to use this

   If the printer is locked, or if you have specified a file name that

    var Y

    Procedure WriteSquared (X)
       Writeln (X * X)

    Example:
       Y = Loc(WriteSquared)
       Run Y(3)   ; This will write a 9 on the screen

   Warning! Don't put the variable you are running in parentheses.

   SavePosition (On/Off)   SavePosition (On/Off)   SavePosition (On/Off)
   If SavePosition is On, MarxMenu will return to the last menu selection
   you made when MarxMenu is re-entered. As you select menu layers your
   keystrokes are stored in an internal string variable called KeySave. On
   exit, MarxMenu writes KeySave to an environment variable KSV. On return
   to MarxMenu, this variable is retrieved. The return point may be altered
   by using the command KeySave = (string).

   Another thing this points out is that environment variables can be used
   to store information and allow MarxMenu to remember things from one
   selection to another. Since MarxMenu doesn't stay memory resident, this
   is the only way I have found to store information.

   Shared   Shared   Shared
   The key word SHARED can be used to define variables just like VAR. Any
   variable defined with SHARED is passed globally to and from overlays.

   The important thing is that the Shared variables must be defined exactly
   the same way between the overlays. There is also a pre-defined variable
   called COMMON. Technically, Shared variables are qualifiers off of
   COMMON.

   ShellEnvironment   ShellEnvironment   ShellEnvironment
   ShellEnvironment selects the environment of the last COMMAND.COM in
   memory for use with environment access commands. This is usually the
   same as the Master Environment.

   More than one COMMAND.COM is loaded when you are running a shell under
   WINDOWS or DESQVIEW. When using these programs, you will want to access
   the Shell Envoronment instead of the Master Environment. The Shell
   Environment is the one that will run batch files.

   Tone (Frequency,Duration)   Tone (Frequency,Duration)   Tone (Frequency,Duration)
   This command plays a note at Frequency cycles per second for a period of
   Duration 1/18 of a second. The reason it is in 1/18 seconds is because
   there is a standard interrupt that gives me that time period. The IBM
   series computers are not music oriented machines so don't throw away
   your Compact Disk player.

   The maximum duration is 255 1/18 of a second. Normally, MarxMenu will
   create a break in between notes equal to 1/8 of the duration of the
   note. If you want to eliminate the break and create a 'slur' (music
   term), add 256 to the duration. This tells MarxMenu to connect the notes
   without a break.

   UseArrows   UseArrows   UseArrows
   UseArrows tells MarxMenu that the selection will be made by moving an
   inverse video bar over the selections. No parameters are required for
   this command to work. It will pick the first line with a capital letter
   as the first menu selection. All text in the window must be indented at
   least one space and there must be one space between the end of the line
   and the right wall of the window. Multiple items on the same line must
   be separated by two or more spaces.

   The OnKey selection is triggered by either the first capital letter in
   the selection or by a number from 0 - 9 or some punctuation characters.
   This number or letter will be a different color if you use the CapsColor
   command. (See Also: PULL.MNU for an example).

   UseArrows Off will disable this feature.

   UseCommand (on/off)   UseCommand (on/off)   UseCommand (on/off)
   Used with Execute. Will load COMMAND.COM before running the specified
   program. Not as fast, because the system has to find and load
   COMMAND.COM, then the specified program. The advantage is if COMMAND.COM
   is loaded, it will automatically search the DOS path for the file to be
   executed by the Execute command.

    Example:
      OnKey 'D'
      |UseCommand On
      |Execute 'DM'

   The default is OFF.
