ISSUE

     NOVELL DOS 7 has greatly enhanced CONFIG and BATCH commands.
     This document provides examples of how these various
     commands can be used.  For more information on batch file
     commands and syntax refer to DOSBOOK, the NOVELL DOS 7
     online User Guide.  Also reading the following chapters from
     DOSBOOK would be particularly helpful:

          Chapter 7, "Batch Processing"
          Chapter 8, "Command Reference"
          Chapter 9, "Configuring the System"

     Batch commands that were added since DR DOS 6.0 are the
     following:

     ?         Allows a yes or no branch in the same manner as
               the "?" in the DR DOS 6.0 CONFIG.SYS command.

     DIREXIST  Added to evaluate whether a directory exists.

     CHOICE    Returns an error level for evaluation.

     Only the basic ideas are outlined in each example that
     follows.  A batch file that illustrates the new NOVELL DOS 7
     commands and their use is at the end of this document.


     EXAMPLE 1 - THE USE OF GOTO IN THE CONFIG.SYS FILE

     ?"Do you want to run QEMM (y/n)? " goto QEMM
     ?"Do you want to run MemoryMAX (y/n)? " goto NWDOS


     :QEMM
     DEVICE=C:\QTR_DECK\QEMM386.SYS
     DEVICE=C:\NWDOS\HIMEM.SYS
     (additional QEMM driver lines go here...)
     goto COMMON

     :NWDOS
     DOS=UMB
     DEVICE=C:\NWDOS\EMM386.EXE /F=AUTO...
     ...

     :COMMON
     files=40
     buffers=20

     The GOTO statement is used to proceed directly to a label.
     This function works similar to the GOTO statement found in
     batch file processing.


     EXAMPLE 2 - THE USE OF CHAIN IN THE CONFIG.SYS FILE

     This example shows that you can link to other files that
     hold your configurations for each system setup.  In the
     following CONFIG.SYS file, the two lines direct the
     configuration process to the QCONFIG and MCONFIG.SYS files.
     The appropriate FILES, BUFFERS, and so forth, information is
     contained within those files and not within the main
     CONFIG.SYS file.  If the response to both questions is no, a
     default configuration begins.  The RETURN command cannot be
     used to return to the parent CONFIG.SYS file.

     ?"Do you want to run QEMM (y/n)? " chain=QCONFIG.SYS
     ?"Do you want to run MemoryMAX (y/n)? " chain=MCONFIG.SYS
     files=40
     buffers=20


     EXAMPLE 3 - USING "?" IN BATCH FILES

     When you run a batch file containing a "?" statement, a
     response to the prompt is required by the user before
     processing continues.

     Please note that the maximum length of a batch file
     statement (including the ?) is 128 characters.

     The following statement in a batch file causes the system to
     prompt the user before deleting all the files with the
     extension .OLD from C:\ACCOUNTS:

     ?DEL C:\ACCOUNTS\*.OLD

     So, when the file executes, the user sees the following
     prompt:

     DEL C:\ACCOUNTS\*.OLD (Y/N) ?

     If the user answers Y, the DEL command is run and the files
     are deleted.  If the user answers N, the command is ignored
     and the next line in the batch file is processed.

     EXAMPLE 4 - USING SWITCH/RETURN AND LABELS

     Processing pauses on the SWITCH command until an option is
     chosen.  The appropriate option is selected by choosing a
     number.  The SWITCH command then goes to the corresponding
     label.  In the following example, 1 selects the label :XMS,
     2 selects the label :EMS, and so forth. The RETURN command
     will return processing to the line after SWITCH.  Notice the
     use of the ECHO statement for setting up the menu options.

     ECHO =        Choose which Memory you want and how to use it
     ECHO =
     ECHO =          1 (or ENTER)    XMS Memory
     ECHO =          2               EMS Memory
     ECHO =          3               DPMI ON, XMS
     ECHO =          4               DPMI ON, EMS
     ECHO =
     ECHO =         Make your selection...

     SWITCH XMS, EMS, DPMI_ON1, DPMI_ON2
     GOTO DEFAULTS

     :XMS
     DEVICE=C:\NWDOS\EMM386.EXE /F=NONE /R=AUTO
     RETURN

     :EMS
     DEVICE=C:\NWDOS\EMM386.EXE /F=AUTO /R=AUTO
     RETURN

     :DPMI_ON1
     DEVICE=C:\NWDOS\EMM386.EXE /F=NONE /R=AUTO /DPMI=ON
     RETURN

     :DPMI_ON2
     DEVICE=C:\NWDOS\EMM386.EXE /F=AUTO /R=AUTO /DPMI=ON
     RETURN

     :DEFAULTS
     SHELL=C:\COMMAND.COM \C: /P /E:512
     BUFFERS=20
     FILES=30
     DEVICEHIGH=C:\NWDOS\DPMS.EXE
     etc...


     EXAMPLE 5 - HOW TO USE ENVIRONMENT VARIABLES IN THE
     CONFIG.SYS

     The use of variables in the CONFIG.SYS file is not quite the
     same as in batch files.  Because the command processor
     (COMMAND.COM) is not loaded until after the command in the
     CONFIG.SYS file have been processed, the environment
     variables are only stored.  These variables are then passed
     to the command processor, where they can be tested and
     processed through the AUTOEXEC.BAT file or other batch
     files.  Testing an environment variable is not possible in
     the CONFIG.SYS file.  The CLS, CPOS, EXIT and SET commands
     are featured in this example:


     :DEFAULTS
     SHELL=C:\COMMAND.COM \C: /P /E:512
     BUFFERS=20
     FILES=30
     etc....

     ECHO = Choose which TSRs and Utilities you want loaded at
     BOOT
     ECHO = time for this session.
     ECHO =
     ECHO =         1 (or ENTER)   None... just continue
     ECHO =         2              Mouse & Cursor Drivers
     ECHO =         3              Keyboard "Speeder"
     ECHO =         4              Novell Network
     ECHO =         5              Done with selections
     ECHO =
     ECHO =         Make your selection...

     :MORE
     CPOS 10,33
     SWITCH NOTHING, CURSMOUS, SPEEDKEY, NOVELL, DONE
     GOTO MORE

     :NOTHING
     :DONE
     CLS
     EXIT

     :CURSMOUS
     SET THINGS=ON
     RETURN

     :SPEEDKEY
     SET SPEEDKEY=ON
     RETURN

     :NOVELL
     SET NETWORK=ON
     RETURN

     The AUTOEXEC.BAT file now allows testing of the environment
     variables and executes commands based upon the conditionals
     illustrated below:

     @ECHO OFF
     VERIFY OFF
     PATH C:\;C:\NWDOS;C:\BATS;C:\TOOLS;C:\WINDOWS
     if "%things%"=="on" prompt
       $e[s$e[0;70H$e[1;36m$t$e[u$e[1;36mDRDOS6$p$g$e[2;32m
     if not "%things%"=="on" PROMPT [NOVELL DOS 7] $P$G
     SET TEMP=C:\TEMP
     IF NOT "%TEMP%"=="" MD %TEMP% >NUL
     if "%things%"=="on" LH MOUSE
     if "%things%"=="on" LH CURSOR /s10
     if "%speedkey%"=="on" c:\nwdos\mode con:rate=30 delay=1
     if "%network%"=="on" LH c:\lan\ipx
     if "%network%"=="on" LH c:\lan\net3



     EXAMPLE 6 - THE CHOICE COMMAND IN BATCH FILES

     The CHOICE command is an external program that returns an
     ERRORLEVEL for certain preselected keys.  They can then be
     tested with IF to make branches in a batch file.  Up to 99
     different errors can be returned.  Three lines were used to
     create this example:

     CHOICE /C:XY Select X or Y for a message ...
     CLS
     IF ERRORLEVEL 2 ECHO MESSAGE: CHOICE RETURNED AN ERRORLEVEL
     OF 2
     IF ERRORLEVEL 1 ECHO MESSAGE: CHOICE RETURNED AN ERRORLEVEL
     OF 1

     The switch /C:XY instructs choice to use the keys X and Y.
     They are not case sensitive.  The letter X will be
     errorlevel 1 and Y will be errorlevel 2.

     The remaining text is the displayed message.   Because you
     chose the letter Y you actually received two messages.  This
     points out one of the tricks to using ERRORLEVEL.  When the
     ERRORLEVEL is tested, a logic is used that considers the
     statement to be true if the value is equal to or greater
     than the returned error.

     In the example used here:  ERRORLEVEL=2 (letter Y), is true
     so the message is displayed.  The second statement IF
     ERRORLEVEL 1 is also true (because the returned value of 2
     is greater than or equal to 1) so the message is displayed.

     You should always perform the IF tests beginning with the
     highest ERRORLEVEL first.  This is because the IF evaluates
     the statement based on whether the returned value is equal
     or greater than the IF statement.

     In the example used here:  ERRORLEVEL=1 (letter X).  The
     first statement IF ERRORLEVEL 2 is FALSE, so the message is
     not displayed.  The second statement IF ERRORLEVEL 1 is true
     so the message is displayed.

     This example used an ECHO; however, a GOTO works best on
     ERRORLEVEL.  This prevents you from going to the next IF
     ERRORLEVEL (which is 0 and will also be true).  The syntax
     for the GOTO is:

     IF ERRORLEVEL 2 GOTO label2
     IF ERRORLEVEL 1 GOTO label1

     :label2
     ECHO = CHOICE RETURNED AN ERRORLEVEL OF 2

     :label1
     ECHO = CHOICE RETURNED AN ERRORLEVEL OF 1


     EXAMPLE 7 - DIREXIST IN THE IF COMMAND

     This command when used with IF will check to see if a
     directory exists:

          IF DIREXIST F:\ GOTO [:label]

     The DIREXIST command can be used to test for the existence
     of drives such as DISK's as well as any subdirectory on a
     disk.  All disk drive have a root directory, so testing for
     F:\ (as in this example) will test for the existence of the
     drive as well as the directory.  Network drives can be
     tested.


     OTHER EXAMPLES

     1.   Selecting different configuration options from the
          CONFIG.SYS file using the ? command.

          ?SHELL=C:\COMMAND.COM C:\ /P /E:512
          ?SHELL=C:\COMMAND.COM C:\ /P /E:1024
          ?BREAK=OFF
          ?BREAK=ON
          BUFFERS=20
          FILES=20
          ?HISTORY=ON, 256, ON, OFF, OFF
          ?DEVICE=C:\NWDOS\ANSI.SYS

     2.   Selecting different AUTOEXEC.BAT's from CONFIG.SYS
          using the ? and the SHELL statement.  In the SHELL
          statement the /P switch can be followed by a file name.
          When present, the named file will be executed instead
          of the AUTOEXEC.BAT file.  The named file must have a
          .BAT extension and cannot exceed 11 characters
          including path.

          ?"Default Autoexec? (y/n) "SHELL=C:\COMMAND.COM C:\ /P
          /E:256 ?"Alternate Autoexec? (y/n)
          "SHELL=C:\COMMAND.COM C:\ /P:ALTERNAT.BAT /E:256

     3.   Selecting and using different configuration files from
          CONFIG.SYS at bootup.

          ?"Do you want to run Windows? (y/n) " chain =
          WCONFIG.SYS
          ?"Do you want to use QEMM? (y/n) " chain = QCONFIG.SYS
          ?"Do you want to use MemoryMAX? (y/n) " chain =
          MCONFIG.SYS
          ?"Do you want to use 386MAX? (y/n) " chain =
          386CONF.SYS

          Each line is printed on the screen and you are asked to
          load and run the chained configuration file.  Each
          configuration file is a complete CONFIG.SYS type file
          with all the appropriate options.

     4.   The above configuration using "menu" choices with
          SWITCH.  Note how the "SET environment" variables can
          be used and tested for different AUTOEXEC type files in
          this example.

          CONFIG.SYS

          ECHO =    1  For Windows Configuration
          ECHO =    2  For QEMM Configuration
          ECHO =    3  For NOVELL DOS 7 MemoryMAX Configuration
          ECHO =    4  For 386MAX Configuration

          ECHO =    5  For no Configuration... just exit
          SWITCH win, qemm, memm, 386m, none
          :none

          set autoexec=norm
          exit

          :win
          set autoexec=win
          chain=wconfig.sys

          :qemm
          set autoexec=qemm
          chain=qconfig.sys

          :memm
          set autoexec=memm
          chain=mconfig.sys

          :386m
          set autoexec=386m
          chain=386conf.sys


          AUTOEXEC.BAT

          @echo off
          PATH C:\NWDOS;C:\;C:\UTIL;
          VERIFY OFF
          PROMPT $P$G
          DISKMAP C: D:
          IF "%autoexec%"=="norm" goto NWDOSEXIT
          SHARE /L:40
          IF "%autoexec%"=="win" SUPERPCK /EM /L:2048
          IF "%autoexec%"=="qemm" CALL QEMM.BAT
          IF "%autoexec%"=="memm" SUPERPCK  /A /L:2048
          IF "%autoexec%"=="386m" CALL 386.BAT
          :NWDOSEXIT

     5.   Using ANSI

          ANSI escape sequences can be used in batch file
          processing to create colorful menus.  Below is an
          example of a menu that uses the SWITCH command and ANSI
          escape sequences to create a menu.  ANSI.SYS must be
          loaded in the CONFIG.SYS file to allow for cursor
          positioning and colors.

          The first character after the Echo statement is an
          ASCII 27 or escape character.  This character may be
          displayed differently on some printers and monitors (in
          fact if you have ANSI loaded you will never see the
          character when typed to the screen).

          To type this character using the NOVELL DOS 7 EDIT,
          press the <Ctrl>+<P> then the ESC key.  An alternate
          method is to press <CTRL>+Q then the N key and then
          type the number 27.  Within EDIT, the ESC character
          will appear as:  ^[.


          If you have downloaded this document from CompuServe or
          the Novell Desktop System Group BBS, the escape
          sequences have been left intact and you can use the
          NOVELL DOS 7 EDIT to block out the Echo statements to a
          file.  Then, if ANSI is loaded when the file is typed
          to the screen, you should see white letters on a
          magenta background.

          For additional information on ANSI.SYS and escape
          sequences, refer to Chapter 9 of DOSBOOK, the NOVELL
          DOS 7 online User Guide.

     SAMPLE.BAT

     If you have gotten this file from CompuServe or the NOVELL
     Desktop Systems Group BBS, you can run this sample batch
     file.

     Starting on the next line, mark a block to the end of file
     (excluding any word processor control characters) and write
     the block to a new file called SAMPLE.BAT.  From the command
     prompt SAMPLE will run the file.

     ECHO IF statements are only executed if TRUE.  The

     ECHO because at first glance it looks true.  However,

     ECHO you are ready to continue.

     IF ERRORLEVEL 2 ECHO Because you chose the letter Y you
     actually received two messages.
     IF ERRORLEVEL 2 ECHO This points out one of the tricks to
     using ERRORLEVEL. When the
     IF ERRORLEVEL 2 ECHO ERRORLEVEL is tested a logic is used
     that considers the statement to be
     IF ERRORLEVEL 2 ECHO true if the value is equal to or
     greater than the returned error.  In the
     IF ERRORLEVEL 2 ECHO example used here: ERRORLEVEL=2 (letter
     Y),
     IF ERRORLEVEL 2 ECHO is true so the message is displayed.

     The second statement
     IF ERRORLEVEL 2 ECHO IF ERRORLEVEL 1 is also true (because
     the returned value of 2 is greater
     IF ERRORLEVEL 2 ECHO than or equal to 1) so the message is
     displayed.
     IF ERRORLEVEL 2 GOTO ERROR2

     IF ERRORLEVEL 1 ECHO You should always perform the IF tests
     beginning with the highest
     IF ERRORLEVEL 1 ECHO ERRORLEVEL first.  This is because the
     IF evaluates the statement based
     IF ERRORLEVEL 1 ECHO on whether the returned value is equal

     IF ERRORLEVEL 1 ECHO IF ERRORLEVEL 2 is FALSE so the message
     is not displayed. The second
     IF ERRORLEVEL 1 ECHO statement IF ERRORLEVEL 1 is true so
     the message is displayed.  This
     IF ERRORLEVEL 1 ECHO example used an ECHO but a GOTO works
     best on ERRORLEVEL.  This prevents
     IF ERRORLEVEL 1 ECHO you from going to the next IF
     ERRORLEVEL (which is 0 and will also be
     IF ERRORLEVEL 1 ECHO true).  EDIT this batch file to see how
     the tests are performed.
