1 PREREQUISITES.
1.1 THE TONY DISK.
I have NO idea who you are, how you got your hands on this, and what
you think about all this, but I DO know that if all you have is a
printed bunch of paper with this article printed upon it, you're out of
luck. You MUST have a diskette with the entire collection of files that
go with this article, or have access to one. I'm going to call it the
Tony diskette.
If you DON'T have access to that collection of files, you should
call up the CHICAGO Bulletin Board run by GENE PLANTZ with your modem
and communications software and become a paid-up member of the bulletin
board.
Here are the necessary parameters:
PHONE NUMBER: (312) 885-9557
BAUD RATE: 1200
PARITY: NONE
LENGTH: 8
STOP BITS: 1
If you would like to leave an electronic message for me, my ID
number is ID1018.
Once you've done that, (S)can for my ID number, and you'll see a few
other articles I've sent up to Gene recently.
This one is called FNDATION.ARC.
Download these files using whatever protocol is appropriate for your
software. You should ALSO download the newest version of the ARChive
command. I use ARC430.EXE, which is version 4.3. The ARChive command
is GREAT! I created and collected many little files. These files
collectively take up a lot of space. I ran the ARChive command, and
each file was crunched and squeezed and then added to one big file,
which has a name that ends with .ARC. If you also have a recent version
of the ARChive command, you can take that big file and have it extract
the files within it.
1.2 TEXT EDITOR.
This article has been created with Symphony, re-arranged with its
Text Outliner, occasionally improved with its Spelling Checker, made
ready for sending out into the world with EDIX 4.02, and ARChived with
ARC430. This was ONLY done for this article! If you're going to
playing with DOS on a daily basis, you had BETTER use a GOOD text
editor! There are no excuses for using Wordstar in non-document mode,
when EDIX is lots easier, MANY times more appropriate and powerful, and
works in any subdirectory.
Here's how to get it legally. (It's worth many times the price).

If you already use a text editor that has everything you've needed in
the past, here are the things you're going to need for my articles:
- Ability to generate an "" ESCape character (ASCII 27) on the screen.
- Ability to edit (create boxes with) the upper 128 ASCII characters,
such as:
201 203 205 187
╔═ ═╦═ ═══ ═╗ ╔═════╦══════════╗
║ ║ ║ ║
186 ║ ║ 186 ║ ║ ║

204 ╠═ ║ ═╣ 185 ║ ║ ║
║ ║ ║ ║
╚═ ═══ ═╩═ ═╝ ╚═════╩══════════╝

200 207 205 188
I have used those fancy characters throughout this article, but
those characters are usually not printed correctly on a typical printer.
Here's the news on how to create those graphics characters. If you have
an IBM brand computer, you received a green BASIC manual along with your
computer. Open up that manual to its APPENDICES (you'll see the pages
numbered A-1, G-2, etc.) and look for the appendix called ASCII Character
Codes. Notice all of those characters and columns of numbers. Here's how
to use them:
Make sure that you're now looking at a DOS prompt (the one that looks
like A> or B> or C>, etc). Notice that the number 205 corresponds to a
symbol that looks like two horizontal bars, one above the other.
Just like this: ═
Hold down the left <Shift> key and the <Alt> key simultaneously, and
type the number 205 on the numeric keypad at the far right of the keyboard
(NOT the numbers on the top row of the keyboard. Let go of the <Alt> key,
and you should see the symbol appear on the screen. Do it again, and
notice that you are building a longer line of two horizontal parallel
lines. Now try a few other symbols, including 186, 201, 203, 205, 187,
206, 204, and 185.
Please remember that not every text editor or word processor will
allow you to create these symbols. Wordstar, for one, will put a great big
M on the screen if you type <Alt> 205. That's why I lean towards the text
editor called EDIX.
1.3 DISK OPERATING SYSTEM.
You may as well upgrade if you're using DOS 2.00 or or 2.10 or 2.11.
As of this writing, the best DOS I've found is PC-DOS 3.10. It's
the newest version, there's VERY few bugs to bite you, and it's got a
snappy feature that makes me smile... Using the Norton Utilities*, you
can UnErase a file much later than with DOS Two Point Whatever. With
the older versions, if you just erased a file, you had better get it
back with UnErase muy pronto, before you save anything else onto the
disk. With DOS 3.00 and 3.10 you've got a little more leeway. I've
UnErased my lost files HOURS later in some cases!

themselves over and over: The Norton Utilities

1.4 HARDWARE.
MINIMUM hardware requirements for ANY OF MY ARTICLES:
1.4.1 COMPUTER.
An IBM Personal Computer or compatible computer (such as a COMPAQ or
CORONA or others) with one floppy disk drive (referred to as drive A:)
and one Fixed Disk (sometimes called a hard disk, but we'll call it
drive C:). If you've got more firepower, so much the better.
You MUST be able to start up your computer and get to a C> or
possibly D> prompt if this article is to make any sense to you. If your
system refuses to start up and get to that kind of prompt, I advise you
to contact the person(s) who sold the system to you, and have them do it
for you. It's a simple courtesy, and they owe it to you.
1.4.2 HARD DISK.
If you haven't gotten a hard disk yet, these articles are NOT going
to do you much good! If you only have a 10 megabyte hard disk, you'll
hit critical mass before too long unless you're VERY careful.
The bigger the better, I always say.
1.4.3 MEMORY.
If you've got an AT with the built-in 512k of RAM, you have an excuse
for having less than 640k of memory. All others must go out and stock
up on inexpensive memory chips and boards. The more USEABLE memory, the
better. If you're going to add more than 640k to your machine, do it
right! Make sure your add-on memory boards support the
Lotus\Intel\Microsoft "EMS" standard. Anything else is just a drain of
power, and won't be useable when the newer versions of DOS come out.
1.4.4 BUILT-IN CLOCK.
I also assume you have a built-in clock in your computer, and you know
how to get at it through software. It's essential that we be able to
date-and-time-stamp our work so we can figure out which copy of our
letter to Mom is the most recent one.
These battery-powered clocks are currently built-into the better and
newer machines like the IBM AT and Compaq 286 series. These are
designed to AUTOMATICALLY provide DOS with the date and time. If you
have an older-type machine, and have the necessary memory expansion to
bring your memory up to at least 640k, chances are that you have one of
these clocks on the add-on memory board. Look in that memory board's
manual and on the diskette that came with it to figure out what software
command on that disk provides tha accurate date and time.
For example: I have a Persyst memory board in my machine, and I need
CLOCK.COM to load the date and time into DOS, and the proper command to
activate it is
CLOCK/S >NUL The /s means to provide DOS with the current date
and time, and the >NUL is a fussy way of making it
do its stuff without advertising itself. I'll cover more about this
in the REDIRECTION OF STANDARD OUTPUT section.
1.5 SOFTWARE.
I'll make NO further enemies during this article if I can help it, so
there will be no preaching about what application software is the best.
DOS tools don't count. I'll speak out on those any day.
I'm going to assume that you have an IBM PC AT with one hard disk. I'm
also going to assume that you have a strong desire to have the software
package called Symphony installed properly on your disk, and you are using
IBM PC DOS 3.10 as a Disk Operating System. I'll assume that you have EDIX
and can use it reasonably well, and that you have access to the freeware
files I include with this article.
2 LESSONS
2.1 UNDERSTANDING MY INTENTIONS.
HOW TO PREDICT MY INSTRUCTIONAL INTENTIONS. (USE OF THE <ENTER> KEY)
I'm going to be expecting you to use the <enter> key a lot.
This does NOT mean I'm going to mentioning it a lot. If I want you to
type in the dir/w command and press enter, here's how I'll specify my
desire:
DIR/W
Got that? Good! I'll also be wrapping my explanations around the
commands, like this . . .
VERIFY ON means that we want the computer to be doubly
certain that everything it reads from or writes on
any disk is accurate from now on. This seems obvious, but it's NOT
automatically taken care of! It'll warn you of major problems most of
the time. Yes, it DOES slow things down a touch, but we more than make
up for it with the CONFIG.SYS file. Refer to the DSKWATCH command for
more information on keeping a suspicious eye on your diskettes...
2.2 START UP THE COMPUTER.
If you'd like to get going in the most efficient way, here's what I
generally do to bring my clients up to speed. In order to continue, I'm
assuming your hard disk is long since partitioned and formatted. If the
person who sold it to you didn't do it for you, get a good computer
store technician to set it up for you. If you're ALREADY using the
newest version of DOS, skip this next section.
2.2.1 INSTALLING A NEWER VERSION OF DOS.
Get the original DOS 3.10 disk and boot up the computer with it.
Give it the date and time when asked to, and start issuing commands:
VERIFY ON For the reasons stated above.
SYS C: To install the two DOS 3.10 hidden files IBMBIO.COM
and IBMDOS.COM onto the root dirsctory of drive C:
COPY COMMAND.* C: To copy the third file COMMAND.COM to the root
directory of drive C: and thereby make it possible
to start up the computer with the proper version of DOS in memory.
2.2.2 CREATING THE C:\DOS SUBDIRECTORY
MD C:\DOS To create a new subdirectory on drive C:
called DOS, which is going to be our main base
station of operations after we get done. Now, press the letter c,
hit the <F3> function key, and hit enter. This repeated your last DOS
command, but replaced the "m" with a "c". It's as if you manually typed
in
CD C:\DOS
So, now you've got the default drive as the root directory of drive
A: and the directory that's open and ready on drive C: is C:\DOS. You
then start copying EVERYTHING from the plain DOS 3.10 disk into C:\DOS
with
COPY *.* C: But we're going to get rid of all of the typically
useless files that you'll never use in a thousand
years. We'll do that in a little bit. First, we're going to put in the
OTHER DOS 3.10 disk, the one called Supplemental Programs. Unless
you're heavy into assembly language programming, you don't need files
like EXE2BIN.EXE or LINK.EXE, and you CERTAINLY don't want to plug up
your hard disk with mind candy like DONKEY.BAS and SPACE.BAS. So we'll
only copy one of the files onto drive C:
COPY DEBUG.* C: This file (DEBUG.COM) may not be something you'll
personally ever find a million uses for. But, the
major computer magazines are FULL of recipes for cooking up little
programs that can do you a lot of good, and the DEBUG command is the
most popular tool for this these days. Let's keep it.
2.2.3 CLEAN-UP TIME.
It's time to take out the trash. You may WELL disagree with my
opinions, but I'm going to clean out some pretty wretched stuff.
Let's switch over to drive C:
C:
ERASE SELECT.* Useless for real computers.
ERASE KEY*.* Useless unless you live in Italy, etc.
ERASE *.PIF Does ANYBODY use TopView? Really? Not I!
ERASE COMMAND.* It's ALREADY in the root directory. We don't need
it anywhere else.
ERASE GRAFTABL.* Has anybody found a reason to keep this one?
ERASE FDISK.* Useful ONLY on a floppy disk.
ERASE BASIC.* We'll keep BASICA.COM. BASIC.COM is useless.
After this, it all depends heavily on YOUR use of the computer. I
personally don't like COMP.COM, PRINT.COM, DISKCOMP.COM. SHARE.EXE, or
JOIN.EXE, but I could probably find some use for them if somebody could
tell me something impressive about them. There's better software out
there.
This whole process of erasing those files was pretty painless if you
only have to do it on one machine. However, if you do a LOT of cleaning
up after other people's messes, I would STRONGLY urge you to get XTREE.
Here's an excerpt from the ADVERTISEMENT for XTREE:
Executive Systems, Inc. presents...
X T R E E
"Every person who uses computers creates numerous files for storing
information and data. Often, files concerning similar topics can be
found throughout several disks or in a haphazard arrangement on a single
disk. To access any given file, the user must struggle through multiple
directory listings, issue many complex commands, and usually view and
review to remember what's in what and where. This process is confusing
and time consuming."
"MS-DOS provides a useful organizational structure called a directory.
Directories allow the computer user to store files in separate groups on
a disk. The files in a directory are kept distinct from files in other
directories. MS-DOS also allows the user to organize and separate
directories. Each directory on a disk, in addition to containing a
group of files, can have "sub-directories" branching off from it. These
sub-directories can each have their own group of files and
sub-directories, and so on. This directory branching organization is
called a "tree structure." When there is more than one directory on a
disk, to find the way to a particular sub-directory on a disk, the user
specifies a "path" of directory names."
"A drawback of the MS-DOS implementation of the concepts described above
is that as the number of directories and/or files grows, the harder it
is to keep track of them, find the data you need, and to throw away any
unneeded data."
"The purpose of XTREE is to facilitate the file and directory maintenance
process by providing you commands to access, delete, rename, view, move,
list, or show any and all files within any and all directories on your
floppy and hard disks. XTREE presents a "visualization" of the
directories, sub-directories, and files on your disks in clear, graphic
screen displays. Statistical data is also displayed at all times; this
data is updated as you perform your tasks."
"XTREE is a powerful, interactive file management utility for the serious
DOS user. XTREE is available on the IBM PC and other MS-DOS computers.
You can order your copy of the actual program by directly writing to us
or using the telephone information below. We accept Mastercharge, VISA,
and American Express credit cards."

2.2.4 COPYING THE SOFTWARE COMMANDS THAT COME WITH THIS ARTICLE.
The files that end with .COM and .EXE that (hopefully) were included
with this article should ALSO be put into the C:\DOS subdirectory.
We'll be putting the .BAT files in, too, after we decide which ones are
appropriate for you.
If you got this stuff from me on a diskette, just put that diskette
in drive A: and give the following command:
COPY A:*.COM
This will copy all of the files on drive A: that end with .COM, and
let's load one into memory immediately:
DOSEDIT This command will be explained shortly.
2.2.4.1 EXPLAINING THOSE COMMANDS.
FIRST and FOREMOST: I DID N O T create these commands! That's
not my talent (yet). I'm the sort of person who is a tool collector.
Anybody can cut glass, if they have a glasscutter. MY talent is in
creating stained-glass windows and crystal decanters, and then showing
others how to do it. You need more than just tools! I give credit to
the authors in EVERY case where I'm aware of it. PLEASE let me know if
I omitted your name. You deserve a lot of credit if you can create
tools of this quality!
2.2.4.1.1 THE DOSEDIT COMMAND.
This program was found on the San Jose IBM Employee PC Club Bulletin
Board. This documentation was written by Brad Kidder, San Jose. As a
programmer, I have found this program to be one of the most valuable
programs that I have in my library.
DOSEDIT is a simple editor for DOS commands. It can be used with
DOS 1.1 and DOS 2.x. DOSEDIT uses a special set of the keys on the IBM
PC keyboard to allow you to edit the DOS command you are entering or one
of the previous commands that you have entered. It keeps a command
stack of the last 256 characters of commands that you have entered and
you can scroll back and forth through this stack. It also allows you to
edit the current command being displayed. NOTE: 1 or 2 character
commands are not saved.
UP arrow Scrolls backward through the command stack.
DOWN arrow Scrolls forward through the command stack.
ESC Clears the command line.
LEFT arrow Moves the cursor left one position.
RIGHT arrow Moves the cursor right one position.
HOME Moves the cursor to the beginning of the command line.
END Moves the cursor to the end of the command line.
INS Toggles the insert function.
DEL Deletes the character under the cursor.
CTRL-left arrow Moves the cursor left a word at a time.
CTRL-right arrow Moves the cursor right a word at a time.
CTRL-HOME Erases from the beginning of the line to the cursor.
CTRL-END Erases from the cursor to the end of the line.
CTRL-PGUP Erases the command stack.
CTRL-PGDN Erases the displayed entry from the command stack.
BACKSPACE Remains unchanged.
CTRL-Z Puts in an End-of-File (1AH - replaces the F6 key).
The function keys F1-F6 no longer have assigned functions.
Tutorial:
After power on, or <Alt><Ctrl><Del>, from the DOS prompt, enter
DOSEDIT (One time). No message will be returned, only the DOS prompt.
To experiment with DOSEDIT, from the DOS prompt enter:
A> ECHO ONE
A> ECHO TWO
A> ECHO THREE
Now use the up arrow key to see the last command (ECHO THREE).
Again use the up arrow key to see the preceding command (ECHO TWO). Now
press enter to execute that command. Then press the down arrow key to
see the following command (ECHO THREE). Press either the up or down
arrow key several times to see how the commands wrap around. Use the
Esc key to clear the command line. Enter new commands and use the
control keys defined above to become familiar with all the functions.
2.2.4.1.2 THE DSKWATCH COMMAND.
--------------------------------------------------------------------------
POWERFUL MEDICINE! If things are inexplicably giving you fits
with the files on your floppy disks, and you deeply suspect the quality
and integrity of your disk drives, THIS is the command to load into your
AUTOEXEC.BAT file! It works intimately with the NEC chip that controls
the disk drives, and pays attention to the error messages that the chip
gives (which we humans normally never hear about). When the disk drive
controller runs into a problem, we normally can only catch the GROSS
errors by giving the VERIFY ON command in our AUTOEXEC.BAT or by typing
it in at the DOS prompt. The DSKWATCH command detects the subtle
errors, and silently puts one of the following messages on the upper
right corner of the screen: Disk error: No response
Disk error: Failed Seek
Disk error: NEC Error
Disk error: Bad CRC Seen
Disk error: DMA Overrun
Disk error: Impos Sector
Disk error: No Addr Mark
Disk error: W. Protected
Disk error: Err Unknown
If you load DSKWATCH into memory, you'll be seeing a lot of these
messages, even if your floppy disk drives and controller are completely
healthy. It helped ME to figure out that a fluorescent light near my
floppy drives was magnetic enough to randomly wipe out my disks... I
KNEW I had a problem, because my disks were going belly-up without
warning. The DSKWATCH command was giving me error messages like crazy,
and I kept eliminating the possible problems, creating new disks and
doing my usual work, until the DSKWATCH command dramatically decreased
its complaints. Now I only get error messages when formatting a new
disk or booting up copy-protected software.
2.2.4.1.3 THE FINDDUPE COMMAND.
SOURCE: Karson W. Morrison Feb. 13,1985
FORMAT: finddupe
This is great for finding extra copies of files that may be plugging
up your hard disk. It's easy to use, too!
OPTIONS:
List the entire directory of the disk: (1)
List only Duplicate files on the disk: (2)
For output on printer enter (P) prior to number option
2.2.4.1.4 THE FLIP COMMAND.
This command is great in a batch file. Some basica files require all
capital letters for input, or you might be in the habit of turning on
the numeric lock when you use a program like Lotus 123.
here's how to use flip.com:
FLIP CAPS ON
FLIP CAPS OFF
FLIP NUM ON
FLIP NUM OFF
FLIP MONO
FLIP COLOR 80
FLIP COLOR 40
2.2.4.1.5 THE LIST COMMAND.
PURPOSE: Provides a GREAT way of scanning through a text file or group
of files. Replaces the TYPE command. Displays the contents of an ASCII
text file, line by line with the aid of scrolling and positioning
commands. An ASCII file of any size may be listed.
FORMAT: LIST [d:][path]filename[.ext]
EXAMPLE: list C:\dos\*.bat
The "filename" is optional. If omitted, you are prompted to to enter a
filename. You may include drive, path, and wild cards in the file name.
The first file which matches the name is displayed until an end-of-file
character is encountered. Each file which matches the "filename" may be
displayed. LIST was designed to display ASCII files. That is, files
which contain text and not binary or control codes. Text characters
usually range from a value of 32 to 127. Characters below 32 (a blank)
are replaced with a funny character to indicate that a non-displayable
character has been encountered. This character is an upside-down
question mark.
If you desire help while LISTing a file, simply press ? and
you'll get a screenful of help concerning commands.
2.2.4.1.6 THE QUERY COMMAND.
Source: Unknown
This was the very first command I found that properly exploited a
nifty little "trap door" in DOS. If you spent much time with the DOS
manual, it BRIEFLY mentions the concept of "errorlevels". I'm not
embarassed to say that I haven't got a clue what an errorlevel looks
like, but I know what it does, so I'll describe it MY way. I think of
an errorlevel as a "mailbox" in memory. The DOS manual tells us how to
LOOK INTO that mailbox, but it tells us that only the BACKUP and RESTORE
commands can put anything into it. If we use a program to put a
particular number into that mailbox, that's called "setting the
errorlevel". Using the Query command, we can write clever batch files
that can branch in any direction we want, just by setting the errorlevel
and referring to it later. I use this in the F.BAT batch file.
2.2.4.1.7 THE REBEEP COMMAND.
Source: Unknown
Best used in a batch file. All it does is beep its fool head off
until you press any key to continue. I use it to signal disaster in the
F.BAT batch file.
2.2.4.1.8 THE RENDIR COMMAND
Source: Unknown
This is a VERY simple program to use! It's a way to rename those pesky
subdirectories, without any fuss or bother. The RENDIR command works
just like the RENAME command, only it's a bit dumber. It DOESN'T know
about paths and such, so it needs to be in the directory that contains
the name of the subdirectory to be renamed. Here's how I use it....
You have RENDIR.COM in a subdirectory on drive C: called C:\DOS, and you
have issued a PATH command in your AUTOEXEC.BAT file saying:
PATH=C:\DOS
and you now can use the RENDIR command in ANY subdirectory... You then
realize that you have a subdirectory on drive C: called C:\LOTUS. This
is a dopey name, because you have Lotus 123 and Lotus Symphony on the
same hard disk, and Symphony is in its own subdirectory, called
C:\SYMPHONY. You now get a wild urge to rename the C:\LOTUS
subdirectory as C:\123 (after all, NOBODY calls the program "lotus"
anymore, they call it 123!). So, you issue the following commands:
C: To make sure you're on drive C:
CD\ To change over to the root directory
DIR *. to look at the directory names
RENDIR LOTUS 123 to rename the \Lotus subdirectory as \123
DIR *. to admire your work.
2.2.4.1.9 THE SCRNSAVE COMMAND.
Source: Unknown
This is a good utility for people who leave their computers on all
day. I once helped a client who brought me his computer, which had a
badly etched screen. His company used Lotus 123 all day, and when the
computer was off, you could still see the spreadsheet BURNED into the
screen phosphors, ruining them forever!
FORMAT: scrnsave 6 (the 6 can be replaced by any number from 1 to 9)
The 6 means that six minutes after you last touched the keyboard,
the screen will go blank. As soon as you touch the Alt key, the screen
will go back to the way it was. This is a safe command for IBM
computers with IBM Monochrome or Graphics boards or both, but I'm still
rather wary of using it on Compaq computers or any computer with a
Hercules card. The older versions of the SCRNSAVE command were known to
build up massive amounts of volts in the monitor board, frying the
circuits!
2.2.4.1.10 THE VTREE COMMAND.
Source: PC Magazine
--------------------------------------------------------------------------
This is a "visual tree" command, and it needs to be used on a disk
that has subdirectories on it.
EXAMPLE: vtree
2.2.4.1.11 THE WHEREIS COMMAND.
Source: The original idea is from "Softalk for the IBM Personal
Computer" by John Socha.
PURPOSE: Searches for specified file(s) through all DOS 2.0 and
above directories, listing matching files with their appropriate
directories and sub-directories.
FORMAT: whereis [filename[.ext]]
EXAMPLE: whereis g*.*
The filename or extension can contain wildcards. No matter what the
current directory is, WHEREIS will search the entire disk, and list the
directory(s) where the file resides.
History: This is a revised version of the popular WHEREIS.COM
program. This revision causes the screen to stop scrolling after
displaying 23 lines and to prompt for more. Depressing any key will
resume scrolling for 23 more lines. The revision was designed by John
Tuccio of Westport, Conn. and implemented by Ted Eyrick of San Antonio,
Tx. It will work correctly on the volume on which it is resident. It
does not automatically cross over onto other volumes. (Note the absence
of an optional volume label in the format description. The following
examples demonstrate proper usage:
WHEREIS myfile.txt
WHEREIS myfile.*
WHEREIS *.bas
WHEREIS *.*
2.2.5 TREE-STRUCTURED SUBDIRECTORIES.
THE DIAGRAM WE'LL BE REFERRING TO.
You are about to see a drawing of how we're going to set up the
hard disk. Rather than using it as a big box with thousands of manila
folders dumped in at random, we will set it up as a filing cabinet with
drawers. Each drawer MUST have a theme, otherwise you won't be able to
remember where to find your goodies.
First, there's the "Root" directory, called "C:\" Think of it as the
"Top Drawer" of the filing cabinet, (in which we'll allow NO
MISCELLANEOUS DRAWERS!) We DON'T want to put ANYTHING in the root
directory unless it's absolutely necessary, because many hard disks have
a limit to how many files can be created in the root directory. You
might suddenly find this out if you keep receiving the "file creation
error" message. The only files that I consider to be necessary in C:\ are
COMMAND.COM, CONFIG.SYS, and AUTOEXEC.BAT.
Since we'll be using the VTREE command to view the subdirectory
structure, I'll be referring to THIS type of diagram from now on:
┬─ DOS
├─ SYMPHONY
└─ WORKFILE ─────┬─ BUSINESS
├─ PERSONAL
└─ MISC
There are good reasons for wanting to set up the hard disk in this
manner. This way, if you're using Symphony, and you want to choose a
file, you don't have to look through forty files that are used by Lotus
DOS.
Also, it's neater in the long run.
2.2.5.1 DON'T COMPLICATE YOUR LIFE!
This one probably doesn't even need to be mentioned, but I'd like to
head you off if you plan to go berzerk creating sub-sub-sub-
subdirectories. Unless you REALLY enjoy typing or are using excellent
software (like Symphony and XTREE) that makes choosing a subdirectory as
easy as pointing at it, take it easy. We want to keep the hard disk and
our lives as clean and tight as possible.
Since a subdirectory is actually just a file with information about
other files within it, it takes up room (4096 bytes minimum for an XT!).
2.2.5.2 CREATING SUBDIRECTORIES.
Go ahead and issue these commands:
MKDIR \SYMPHONY Creates a subdirectory to contain the files
that teach the computer how to be a multi-talented,
multipurpose machine.
MD \WORKFILE Creates a subdirectory that will be the first
place Symphony will look at whenever it needs to
find one of the files we humans create with Symphony.
MD\WORKFILE\PERSONAL Creates a sub-subdirectory that we can choose
as a storage place for Symphony personal files.
Each line performed the same function, and I wanted you to see that
you ARE allowed a little bit of leeway in how you type in commands. Not
much, but some. We're giving each of our subdirectories a name
consisting of up to 8 characters. (I personally don't use subdirectory
names like WORKFILE.026, which use the entire 11 characters possible.
It's just a matter of taste).
We just created a few subdirectories and a sub-subdirectory. These
are highly desirable, because we don't want 3,000 files tangled in a
heap. Think of it as a filing cabinet with several new drawers: each
drawer has its own name, so we know what it's for, and how to find it.
2.2.5.2.1 CHANGING THE C> PROMPT.
So far, if you're confronted with a typical machine, you're staring
at at VERY unfriendly DOS C> prompt. Enough, already! It's almost time
to make the prompt work for us... First, let's play. Type this in:
PROMPT Wake up, everybody!
If you've never played with the PROMPT command before, the results
from typing this in might alarm you a bit. It means nothing. We've
just changed the standard way DOS sys "Yes, Boss?". No more fun for
now, it's time for WORK. I want the prompt to change to look like THIS:
It's now 13:30 on Thu 9-16-1988
(Current directory is C:\DOS)
C>_
Here's how: type in the next line EXACTLY.
PROMPT It's now $t$h$h$h$h$h$h on $d$_(Current directory is $p)$_$n$g
If you hunt down the proper reference (look in the DOS manual in the
back for the PROMPT command), you'll see that there is a LOT of
information, but no recipes for success. (Does this typify the rest of
the manual? Of course! Maybe they'll bind this article into the next
DOS manual.) The PROMPT etc. stuff up above is my DE-BUGGED, CLEAN AND
PRETTY AND NO-FOOLING MIGHTY DAMNED EFFICIENT way of changing the
prompt.
Here's the explanation:
$t means give us the current time, but it normally
gives us a display like 10:05:06:08. Personally,
I'd rather not look at that. So, we use
$h as a backspace to chew up the unnecessary digits.
$d means we want to see the date, but since we already
know what year it is, we'll get rid of that with
some more $h's.
$_ means "move down to the next line".
$p means we'd like to keep track of WHERE we are in
the hard disk's subdirectory structure. It gives a
running report of our PATH.
$n$g just means give us the standard C> or A> prompt.
2.2.5.3 MOVING THROUGH THE SUBDIRECTORY SYSTEM.
Now that we can see where we are at all times, let's look at the new
directories:
VTREE which should show us a something that looks
like this:
┬─ DOS
├─ SYMPHONY
└─ WORKFILE ────── PERSONAL
Then, we'll take a little tour through the structure...
CD\WORKFILE Which is the standard way of telling DOS to
"close" one drawer (technically referred to as the
"default directory") and open up another one,
called C:\WORKFILE.
Now, let's ask for a directory listing:
DIR and you should see something that looks like:
Volume in drive C is MY TOOLBOX
Directory of C:\WORKFILE
. <DIR> 11-20-85 7:26p
.. <DIR> 11-20-85 7:26p
PERSONAL <DIR> 11-20-85 7:26p
3 File(s) 1018432 bytes free
The top two files are supposed to be ONLY for the internal use of
the computer. In most cases, you can ignore the single-dot file. We've
got PLANS for the double-dot file, which will come in handy in a minute
or so... First, let's create a few more sub-subdirectories:
MD BUSINESS Which creates a sub-subdirectory parallel to the
C:\WORKFILE\PERSONAL subdirectory. We'll check
that by typing in
VTREE to admire our efforts.
MD MISC creates the last of our sub-subdirectories for now,
and we can say
VTREE one more time, just to be compulsive.
2.2.5.3.1 A QUICK WAY TO MOVE DOWN ONE DIRECTORY LEVEL.
CD BUSINESS will move us down one level into the
C:\WORKFILE\BUSINESS subdirectory, and our prompt
should affirm this. This particular command is a VERY snappy way to
save typing while in DOS, because we might normally have to type
CD\WORKFILE\BUSINESS to accomplish the EXACT same thing!
2.2.5.3.2 A QUICK WAY TO MOVE UP ONE DIRECTORY LEVEL.
Now, according to the DOS prompt message, you should be in the
C:\WORKFILE\BUSINESS subdirectory. Let's move UP one level in a simple
way:
CD .. And you'll notice from the prompt message that
you're now back in the C:\WORKFILE subdirectory.
What happened? The ".." file is where DOS keeps track of what's above
it in the tree structure, and we just used it to quickly move UP one
level. Let's do it again...
CD .. NOW you can see that the current directory is C:\,
which is as far up as we can go. If you loaded
the DOSEDIT command a ways back, just hit the up arrow key until we get
to the
CD\WORKFILE command again, add \PERSONAL to it, and press
enter, which is exactly equivalent to the
CD\WORKFILE\PERSONAL command.
2.2.5.3.3 A QUICK WAY TO MOVE SIDEWAYS IN SUBDIRECTORY LEVELS.
If you've been keeping up all along, you should have a prompt that
tells you that you're currently in the C:\WORKFILE\PERSONAL
subdirectory, and we'd like to move SIDEWAYS into the C:\WORKFILE\MISC
subdirectory. Here is a reasonably quick way to do it:
CD ..\MISC which says, (in effect), "go up one level and come
back DOWN one level into the MISC subdirectory next
door".
Now that we're there, we can quit our educational tour and get on
with installing a menu sytem.
2.2.5.4 MENU TEXT FILES
Let's copy a couple of my generic menu text files into the proper
subdirectory:
COPY A:*.TXT \DOS this copies all files that end with .TXT into the
proper subdirectory. Now, let's quit doing our
commands by remote control, and enter the C:\DOS subdirectory ourselves:
CD\DOS Now, let's admire these files...
LIST *.TXT which allows us to non-destructively flip through
all files ending with .TXT, and we can signal when
we're done with each one by hitting the
<ESC> key. Just for the heck of it, as soon as you've
gotten back to a DOS prompt by pressing the <Esc>
key a few times, try these commands:
TYPE MENU.TXT To literally dump the contents of that file on the
screen, and
TYPE MENU2.TXT To display the second, less crucial menu options.
You'll notice that there are only TWO box-shaped menus. Here's why:
2.2.5.4.1 MENU PRACTICALITY: DON'T FORCE A CLIENT TO THINK.
I am NOT being snide by using this opening title... I don't want to
THINK, I want to DO. Let the computer do the left-brain stuff - I'll
handle the creative end. I used to espouse 5 separate menus, all
subdivided into categories: Software, Tutorials, Backup, Diskettes, and
Miscellaneous. You wanna know what happened? 9 out of 10 people never
bothered to hunt through the menus to track down the proper command to
back up the hard disk, and I got tired of it. Now, I just stick to two
menus:
2.2.5.4.2 MENU.TXT
This is our MAIN menu, and it should contain the commands that we use
most often, or SHOULD use most often.
Here's what MENU.TXT should look like:
╔══════╦═════════════════════════════════════════════════════════════╦══════╗
║ MENU ║ Type one of the below and then press Return. ║ MENU ║
╠══════╩═════════════════════════════════════════════════════════════╩══════╣
║ MENU = This menu again. (MENU 2 = Second menu) ║
║ S = Symphony (S OTHER = Tutorial, PrintGraph, Translate) ║
║ ║
║ F = FORMAT a 360k floppy disk in drive a: (F HI = HI-DENSITY) ║
║ DOS = INSTALL DOS on a freshly formatted diskette. ║
║ FULLBACK = Back-up ALL of the information on the hard disk. ║
║ ENDOFDAY = Back-up TODAY'S information from the hard disk. ║
║ LOCKUP = SAFELY TRANSPORT this computer from place to place. ║
╚═══════════════════════════════════════════════════════════════════════════╝
MENU.TXT is what will be the first thing you look at each time you
start up your computer, and hopefully the last thing you'll see as you
turn it off. Due to typical space limitations (and in the interest of
keeping the first menu reasonable decipherable), we have a second menu
to supplement the first:
2.2.5.4.3 MENU2.TXT
The only reason for the second menu is to contain the miscellaneous
commands that are not deathly important, but aren't explained elsewhere.
╔════════╦═════════════════════════════════════════════════════════╦════════╗
║ MENU 2 ║ Type one of the below and then press ─┘ ║ MENU 2 ║
╠════════╩═════════════════════════════════════════════════════════╩════════╣
║ MENU = To see the first help menu again. ║
║ LOCKUP = Make the computer SAFE to move from place to place. ║
║ DISKCOPY A: A: = Make a perfect COPY of a floppy disk. ║
║ CHKDSK/F = ("JANITOR" command) Checks for trash on the hard disk. ║
║ DIRSIZE = Get a DIRectory listing with directory size. ║
║ BACKSTAT = Find out what files haven't been backed-up lately. ║
║ REL *.TXT \DOS = RELocate all files ending with .TXT into C:\DOS ║
║ WHEREIS G*.* = Find all files on the hard disk beginning with G. ║
║ LIST *.TXT = Leisurely view all files ending with .TXT ║
║ FINDDUPE = Easy way to locate duplicate files on hard disk. ║
║ VTREE = Get a Visual TREE of the subdirectories. ║
╚═══════════════════════════════════════════════════════════════════════════╝
Of course, NEITHER of these menus are wriiten in stone. If you are
going to be doing this sort of thing for other people, here is a nice
rule of the road from me to you:
2.2.5.4.4 MENU ETIQUETTE: EASIER TO REMEMBER IS BEST OF ALL.
I've seen a lot of consultants fall short on this one: They've
discovered how to set up a menu, and they make it look like this:
====================================================================
PLEASE CHOOSE ONE OF THE FOLLOWING AND PRESS ENTER:
====================================================================
1 - For Symphony
1x - For Symphony in magenta and green
2 - For dBASE III
2x - For dBASE III with every Prokey macro in the world
====================================================================
This menu was designed for a "Techie" who is used to thinking like a
computer, and I would respectfully like to hit them with a brick when
they do this to a computer that doesn't BELONG to them! I suggest the
following, alternative phrasing for the average end user who is scared
of the computer, (and their replacement who has to learn from THEM!):
====================================================================
PLEASE CHOOSE ONE OF THE FOLLOWING AND PRESS ENTER:
====================================================================
s - For Symphony
s mg - For Symphony in magenta and green
db3 - For dBASE III
db3 4me - For dBASE III with every Prokey macro in the world
====================================================================
In my experience, most computer-timid people would rather have the
machine be friendly, even if it means MORE keystrokes. Yes, it's true.
Besides, if you work on HUNDREDS of computers over a span of a year's
time, how do you expect to SUPPORT the first of these two menus? You'll
waste two hours on the phone (with a fearful client who wiped out your
menus) trying to track down your own bad habits to clean them up. KEEP
IT SIMPLE! And if you really doubt this, ask the user's opinion.
2.2.6 BATCH FILES.
Once again, I expect you to have a DOS prompt on the screen that
tells you that the current directory is C:\DOS. If you have my articles
and various files on a diskette, put that diskette in drive A: and issue
the following command...
COPY A:MENU*.BAT which will copy all batch files beginning with MENU
into the current directory. There should be ONLY
ONE, called MENU.BAT.
On the odd chance you aren't yet familiar with batch files, I'll
give you a quick primer.
2.2.6.1 BATCH FILES, RATHER INADEQUATELY EXPLAINED.
Batch files are a major way of making life easier for ourselves on
IBM/Compatible computers. We've been typing in a lot of commands to DOS
during the course of this article, and I GUARANTEE you'll get sick of
baby-talking to DOS if you're not already. We humans can collect all of
the commands we normally issue into small files. We then can just press
two or a few keys, and the computer kicks into gear, performing these
commands one after the other, saving us many keystrokes. It's our way
of using DOS as a programming language.
2.2.6.1.1 THE MENU BATCH FILE - THE TYPICAL EXAMPLE.
If you issue the following command:
MENU then the first help menu will be placed on the
screen in a nice way. Alternatively,
MENU 2 will place the second help menu on the screen.
This is all accomplished with a single batch file
called MENU.BAT. Let's take a look at it.
TYPE MENU.BAT should show you this:
echo off
cls
C:
cd \dos
if '%1'=='2' goto menu2
type menu.txt
goto end
:menu2
type menu2.txt
:end
I'll explain the new concepts contained in each batch file down
here:
ECHO OFF is used as first line of EVERY batch file, and
nowhere else ever. It means we don't want the
following commands flashed on the screen in a confusing way, so "zip
your lip, computer!"
CLS means "clear the screen". The second command for
EVERY batch file.
C: means that DOS should pay attention to drive C:
from now on. This tells DOS that you want to
"change the default drive", meaning that all of your previous commands
might conceivably have been taking it for granted that drive A: was the
important one, and now drive C: is going to be the important one. This
line is CRUCIAL, but for a hidden reason. I WILL refer to this later
on!
CD\DOS means that DOS should pay attention to the C:\DOS
directory from now on. Important for the same
reason! Time to get off track temporarily:
2.2.6.1.1.1 PARAMETERS.
Good concept, bad name. If I type in the following command:
MENU 2 then the "2" is called a parameter. If we had
phrased our command with a few more parameters,
such as "MENU 2 TEXAS COWBOYS", then "MENU" would be parameter 0, "2"
is parameter 1, "TEXAS" is parameter 2, and "COWBOYS" is parameter 3.
It goes all the way up to parameter 9 if you want. I never go beyond
parameter 2, personally.
2.2.6.1.1.2 REPLACEABLE PARAMETERS.
Once again, here is the line I'm currently explaining:
IF '%1'=='2' GOTO MENU2
The %1 is what is called a "replaceable parameter". I can see
several people fading out of the room when they see this one, but I'll
explain how it works. It's NOT that bad, if it does some good! Loosely
translated, "IF '%1'=='2' GOTO MENU2" means this: "If what the human
being typed in as parameter 1 looks like a number '2', then skip the
next few lines, looking for the address called 'MENU2'. Once you find
it, continue executing the commands you'll find on the next line. If
ther is NOT a '2' at all, or the parameter is anything BUT a '2', just
continue with the next line".
Here's why this can do us some good. Remember how I insisted that
we be careful not to put unnecessary files on any disk? I used to have
two different batch files, one to show the first menu, and one to show
the second menu. I have since discovered how much space those little
files are REALLY taking up. In the November 12, 1985 issue of PC Magazine,
it's mentioned that files containing only 1 byte on a Seagate 20 megabyte
hard disk REALLY take up 8,192 bytes of storage! Using replaceable
parameters, I make each batch file do the work of at least two, and it's only
a little bit slower.
2.2.6.1.1.3 THE MENU BATCH FILE, CONTINUED.
TYPE MENU.TXT displays the first main menu on the screen,
GOTO END means that the next few lines should be skipped,
and as soon as the line that looks like :END is
found, the batch file will continue with the next line, if any.
:MENU2 is only a label that we can branch over to. It
does nothing except sit there, waiting to be looked
for.
TYPE MENU2.TXT displays the second help menu on the screen.
:END is another label we can GOTO.
The MENU.BAT is a reasonable example of how I write my simplest
batch files. If I'm placing notes within my batch files for other
people to learn from, some of my batch files extend to over 100 lines!
If you're using a nice fast computer, that's not much of a problem, but
the delays inherent in a LONG batch file can be pretty prohibitive.
There are some AMAZINGLY complicated ways to break a mega-batch-file
down to only 2 or 3 lines, but that's another article completely.
2.2.6.1.1.4 THE AUTOEXEC.BAT FILE.
Remember how I had you dink around with the PROMPT command? I
consider that to have been a VERY good lead-in to this batch file.
THIS IS THE BIGGIE! Other batch files are A-Okay for saving us a little
work here and there. The AUTOEXEC.BAT file is THE LAW for the computer.
NO FOOLING. Most people haven't got a CLUE about this stuff.
How would you like your computer to run better?
We human beings create the AUTOEXEC.BAT file to make our IBM or
compatible computers work MUCH better on a day-to-day basis. If we are
clever and knowledgeable, we can overcome the worst deficiencies in the
Disk Operating System (DOS).
For instance, you might using a program for several hours, saving
your work onto a storage disk VERY carefully. Just before turning off
the computer, you save your work for the last time. For NO obvious
reason, the data you save is NOT saved correctly. Totally unaware of
this, you turn off the power and go do something else. Next morning,
you attempt to retrieve your work, and are greeted with a loud beep and
an error message saying: "Part of file is missing".
Here's another example: If you've been using your computer for
awhile, you may have tried to stop your computer from printing out
something in error. You may have had the experience that this doesn't
always work as quickly as you would like. The computer stops
misbehaving when it finally feels like getting around to it.
This lesson is NOT guaranteed to completely eradicate such
problems, but it can help provide some peace of mind.
Each time you start up the computer, the Disk Operating System (DOS)
looks for a "batch" file called AUTOEXEC.BAT, containing as many or as
few commands as we desire. DOS then follows these commands, one by
one.
Here's a little preparation for our next step: make sure that the
current directory is C:\DOS, put the diskette with my files in drive A:
and then say
COPY A:*.MSG to copy all message files that end with .MSG into
the current directory. You'll see why shortly, in
the sections explaining the AUTOEXEC.BAT and the
FULLBACK.BAT and ENDOFDAY.BAT files.
The AUTOEXEC.BAT doesn't do us any good unless it's in the C:\
(root) directory, so let's move on up to the top:
CD\
2.2.6.1.1.4.1 DON'T WIPE OUT A PREVIOUS AUTOEXEC.BAT!
We should be in the C:\ directory, and let's CAUTIOUSLY test to see
if there is ALREADY an AUTOEXEC.BAT file in there.
TYPE AUTOEXEC.BAT Might or might not get any results. If you get a
message saying "File not found", we're safe to
issue the next command:
COPY A:AUTOEXEC.BAT if the disk containing my files is in drive A:
If the TYPE command displayed a file on the screen, why don't you
just read along with the rest of us, but restrain yourself from
modifying or adding a new AUTOEXEC.BAT on top of your old one unless you
feel confident about doing it!
2.2.6.1.1.5 THE AUTOEXEC.BAT FILE, CONTINUED.
Here's what my generic AUTOEXEC.BAT looks like:
echo off
cls
date
time
path=C:\dos
cd\dos
break on
verify on
dskwatch
dosedit
scrnsave 6 >nul
prompt It's now $t$h$h$h$h$h$h on $d$_(Current directory is $p)$_$n$g
type backdate.msg
type menu.txt
Again, I'll begin an explanation of the new concepts:
DATE and TIME mean that the computer is going to ask you for the
date and time at this point. THIS IS VERY
IMPORTANT! After you back up your work onto floppy diskettes, you can
tell which diskette contains the most recent copy by looking at the
directory. This can save you from accidentally wiping out or losing
important work.
2.2.6.1.1.5.1 IF YOU HAVE A COMPUTER THAT LACKS A BUILT-IN CLOCK.
This is the ONE time I'm going to lapse from my supposition that
you're using an IBM AT. The DATE and TIME lines are NOT NECESSARY in
the AUTOEXEC.BAT file on newer machines like the IBM AT and the Compaq
Deskpro 286 series! Forget you ever knew they existed! They can get in
your way! I only include those two lines here for those people out
there who DON't have built-in clocks in their machines.
As I was saying much earlier in the HARDWARE MEMORY REQUIREMENTS
section, if your older machine already has at least 320k of RAM, chances
are very good that it contains an additional memory board that has a
battery-powered clock. This memory board came with a diskette,
containing various files. One of these files will automatically enter
the date and time for you. Copy this file to the C:\DOS subdirectory,
and include its name in the AUTOEXEC.BAT file, instead of the DATE and
TIME commands. For example: if you're using an AST Six-Pak Plus memory
board, the proper command is ASTCLOCK. If I were you, I'd replace the
DATE and TIME commands with the ASTCLOCK command, but I'd do it in a
certain way:
2.2.6.1.1.5.2 REDIRECTION OF STANDARD OUTPUT.
This information is a supplement to the DOS manual's "redirection of
standard output" section.
If you manually run the ASTCLOCK command,
ASTCLOCK
You'll get a message on the screen that looks somewhat like this:
Date and time processors loaded
Current time is 02:41:24
Current date is 11-21-85
So, if you're creating a file called AUTOEXEC.BAT and wish to
include the ASTCLOCK command, change the line saying
ASTCLOCK to a line that says
ASTCLOCK >NUL and you'll notice that the date and time are still
being loaded into the computer, but no message is
flashed on the screen.
The > symbol means that we want to dump something to somewhere other
than the usual place, which in this case means the screen. In this
example, we're dumping it out to electronic limbo, which is called NUL
in DOS.
Here's something else to try, just to get a feeling for redirection:
turn on your printer, and issue the folowing DOS command:
DIR >PRN Normally, the output of the DIR command is the
screen, but now it's been temporarily changed to
the printer, called PRN.
2.2.6.1.1.5.3 IMPORTANT KEY TO THIS SYSTEM! THE PATH COMMAND.
PATH=C:\DOS means that we want to give commands, and we want
DOS to follow our commands EVERY time. By giving
the PATH command each time we start up the computer, we're telling DOS
where it can find further information if it doesn't understand us. The
THEME of the C:\DOS subdirectory is that it contains all of our TOOLS
AND GOODIES. DOS will use the news it got from the PATH command to find
any tools and goodies it needs.
I CAN'T stress this strong enough. If the system is set up
properly, using this article's guidelines, you only need to set the PATH
command ONCE in the AUTOEXEC.BAT, to ONE subdirectory, and you'll reap
some benefits:
2.2.6.1.1.5.3.1 BENEFITS: FASTER OPERATION.
Setting a PATH that looks like this:
PATH=C:\;C:batch;C:\PROGRAMS;C:\RBASE;C:\DOS
is certainly possible, but it's HORRIBLY slow, because by the time the
PATH command has finished forcing the hard disk to root through all of
those subdirectories, you could have been growing HAIR as a hobby.
2.2.6.1.1.5.3.2 LESS ERROR MESSAGES.
The PATH command is not normally described this way, but here is the
bottom line: The purpose of the PATH command, if properly set up, is to
make the "Bad command or filename" error message unnecessary. Have YOU
ever seen that message, HMMMMM? I am SO sure!
2.2.6.1.1.5.3.3 EASE OF USE.
If you adhere to my guidelines, all of your batch files will work in
ANY subdirectory, on ANY disk, any time you see a DOS prompt. Period.
2.2.6.1.1.6 THE AUTOEXEC.BAT FILE, CONTINUED AGAIN.
BREAK ON means that we want to reserve the right to panic
and break out of problems we might be experiencing.
Normally, we can tell the computer to "WHOA" by holding down the CTRL
KEY and briefly pressing the SCROLL LOCK or BREAK key on the upper right
corner of the keyboard. (See the word "Break" on the front of the key?)
This procedure will still work, but now we've told the computer to pay
EXTRA-attention to our desire to break out of what's going on.
VERIFY ON means that we want the computer to be doubly
certain that everything it reads from or writes on
any disk is accurate from now on. This seems obvious, but it's NOT
automatically taken care of! It'll warn you of most major malfunctions
while they're happening, no matter what program you're currently
running. The way a VERIFY problem makes itself known is with a message
such as:
Disk read error drive C:
Abort, Retry or Ignore?
As soon as you see that sort of message, you're being expected to
make a decision between those three possible choices. I CAN't give you
a general rule of thumb, but you COULD press 'I' to Ignore the error and
try to figure out what the problem was and how to get around it.
I know I already explained the DSKWATCH command in the section
called THE DSKWATCH COMMAND, but I still think it bears repeating how
much I like this command to partially supplement the VERIFY ON command.
The DOSEDIT and SCRNSAVE commands can be included or deleted from
the AUTOEXEC.BAT without any problem, but you might want to at least
give them a try...
TYPE BACKDATE.MSG is a nice way to get solid information that only
shows up when you start up your computer. It gives
a report on when the information on the hard disk was last backed up.
You'll see it in a moment.
2.2.6.1.1.7 TESTING THE AUTOEXEC BATCH FILE.
Open the drive A: door and hold down the <CTRL><ALT><DEL> again, and
give the computer the date and time if asked to.
The next thing you should see on the screen at this time should be
the following message, supplied by BACKDATE.MSG:
The most recent hard disk backup was performed on... (None so far)
Right under that, you should see the main Menu, and under that there
should be a prompt that looks somewhat like this:
It's now 13:30 on Thu 9-16-1988
(Current directory is C:\DOS)
C>_
2.2.7 THE CONFIG.SYS FILE.
This is NOT exactly a batch file, but it IS a file we humans create,
containing a collection of special commands. The difference is that
these commands are NOT commands that you normally can type in at the DOS
prompt. The CONFIG.SYS file is another "obedience trainer" for your
computer, and its shocking how few people know the value of it. The
file called CONFIG.SYS is read before AUTOEXEC.BAT, and has a different
reason for existence.
When you start up your computer, the Disk Operating System is
loaded into memory. It then looks for a file called CONFIG.SYS on the
start-up disk. If the file exists, then DOS performs the commands that
we human beings have set up for it. After that, the AUTOEXEC.BAT kicks
in.
You can study the technical aspects of the CONFIG.SYS file in
greater detail in your DOS manual's Configuration Commands section.
CONFIG.SYS is great for everyone, but especially for those advanced
computer users who like to have a lot of programs in memory at the same
time. For instance... I have Symphony, Prokey, Sidekick, DOSEDIT, and
the DOSEDIT utility in my computer's RAM memory simultaneously while
writing this article. If I didn't prepare a good CONFIG.SYS file a few
months ago, I could pretty well expect things to start "crashing and
burning". I get distress calls from repair technicians all the time.
Most times it's because they can't pinpoint a problem as a definite
hardware or software problem, and they call me when the shotgun approach
(replacing boards and software and hard disks) has no effect. Nine
times out of ten, the problem can be traced to the lack of a CONFIG.SYS
file.
Here's why: Normally, you can only have up to 8 files open in memory
at one time. Think of this as being able to juggle 8 objects at once:
if your computer tries to "juggle" more than it can handle, things start
crashing and burning, the keyboard locks up solid, stuff like that.
Unpredictable problems are assured. So, we'll talk about the
FILESS statement in your CONFIG.SYS file to find out how to get
around that.
Another benefit of the CONFIG.SYS file is that it will likely make
your hard disk and floppy disks quit making a "wacka wacka wacka" sound.
This is done with the BUFFERS statement.
2.2.7.1 CREATING A CONFIG.SYS FROM THE KEYBOARD.
We're going to create a file called CONFIG.SYS from scratch in the
root directory of the hard disk..
First, let's test to see if there's ALREADY a CONFIG.SYS in your
root directory. Turn on your printer, and issue this command:
TYPE C:\CONFIG.SYS >PRN
If nothing printed out, and the screen shows a "File not found", you
can safely move on to the next paragraph. If the printer printed out
something ELSE, you DEFINITELY want to do some studying before you do
anything that might be hazardous. The process of creating a CONFIG.SYS
file that I'm about to explain would create a NEW file on top of the old
one. This is FINE if you have the printed record of your old file and
combine the old stuff with the new stuff using the next paragraph.
Here's the simplest way to create a fresh, new CONFIG.SYS file.
Type each of these commands, pressing ENTER after each line:
COPY CON CONFIG.SYS
BUFFERS=16 (Refer to next paragraphs if using more than 10
FILES=28 megabytes of storage)...
After the last line, hold down the <CTRL> key and briefly press Z.
This is equivalent to hitting the <F6> key, except the DOSEDIT command
overrides that function. That should put a "^Z" on the screen, which is
an "end of file" character. Then, press ENTER. You'll see your disk
drive's light go on and then off. That means the CONFIG.SYS file has
been created. You can now re-start your computer in the normal fashion,
with invisible but valuable differences...
Here's the explanation:
COPY CON CONFIG.SYS means that we want to copy a file called
CONFIG.SYS from the console (screen) onto the
current disk drive.
BUFFERS=16 is a great way to speed up your computer's disk
accessing. According to the great Peter Norton,
the best number of BUFFERS to assign depend on the type of disk drive
you use the most. If you only use floppy diskettes, you should set the
number of BUFFERS to 8. If you use an IBM PC XT with a 10-megabyte hard
disk, set your BUFFERS to 16. If you use an IBM AT or a Compaq Deskpro
with a 20-megabyte hard disk, set your BUFFERS to 32. I'm only
guessing, but it seems like the progression is 16 BUFFERS to each 10
megabytes.
I've seen a properly set up BUFFERS statement make many hard disks
MUCH quieter and quicker. This is how we more than overcome the speed
disadvantage of the VERIFY ON statement in the AUTOEXEC.BAT file.
FILES=28 means that we want to give DOS the ability to
"juggle" up to 28 files in memory at once if
necessary. This can include memory-resident utilities like Sidekick,
Applications software like Symphony or Framework, Symphony's Tutorial
Application, the Lotus Access Menu, and any other such goodies we might
use during a typical day's work. I've found that 28 is a good number,
though there's no real upper limit to the number you can specify. Each
additional file you add takes up 39 more bytes of RAM memory.
The FILES statement can be especially nice for all of the Symphony
or Framework or dBASE III users who have discovered problems when
combining their application software with various memory-resident
programs like the Pop-Up series and SideKick. You might have noticed
that the computer would inexplicably lock up when you'd have many of
these programs in memory. Being logical and intelligent, you'd stop
using these auxiliary programs.
A PROPERLY set-up FILES statement in the CONFIG.SYS file may clear
up your woes! This is advice that might just cause you to welcome
Sidekick and all of the others back into daily use.
There's LOTS of other things that can go into the CONFIG.SYS file,
but they're REALLY not appropriate in a FOUNDATION article. Well cover
several more goodies real soon! (The articles are already written!)
2.2.8 BATCH FILES, CONTINUED.
Please go ahead and re-start the computer if you haven't already, so
we can continue.
The following batch files are EXTREMELY debugged:
2.2.8.1 THE S.BAT FILE.
In order to use the S.BAT file, we need to be fully prepared to
install Symphony on the hard disk. If you don't use Symphony, and/or
never INTEND to use Symphony, I would still urge you to read through
this section for the newest nuggets of information.
If you HAVE Symphony and use it or would like to, here's what we
need to do:
We're going to install Symphony into the C:\SYMPHONY subdirectory,
and clean out any unnecessary files. At that point, you're going to
have to deal with the copy-protection situation. At the time of this
writing, (Winter 1985), the newest version of Symphony is the debugged
version of Version 1.1. It normally requires a "key disk" in drive A:
each time you begin Symphony, and that's something I have found irking.
If you ALSO find this to be irking, contact these folks. among others:
Quaid Software Limited Central Point Software, Inc.
45 Charles Street East 9700 SW Capitol Highway, #100
Third Floor Portland, OR 97219
Toronto, Ontario M4Y 1S2 (503) 244-5782
(416) 961-8243
If the rumored new version of Symphony really DOES allow you to
install it and run it without a key disk, forget I said anything. We
shall SEE.
Go ahead and issue the following commands:
CD\SYMPHONY and then put the TONY disk in drive A: COPY A:S.BAT
\DOS to copy the S.BAT file into the C:\DOS
subdirectory, whereupon we put one of the Symphony
diskettes in drive A: (any of them) and say
COPY A:*.* to copy all files from A: into C:\SYMPHONY.
Repeat this with each of the Symphony diskettes,
and follow the standard installation procedures in the Symphony manuals.
By the time you're done, you should be back at the DOS prompt, and still
in the C:\SYMPHONY subdirectory. Issue the following commands to clean
up any unnecessary files:
ERASE COMMAND.* You would not BELIEVE how many people don't catch
this one! The COMMAND.COM file belongs in ONE
place... The C:\ directory, and NOWHERE else! I
cleaned up one hard disk that had COMMAND.COM in 17
places on the hard disk!
ERASE *.BAT If you're done with your installation, and you're
using a hard disk, you DON'T need any batch files
in this subdirectory.
ERASE CONFIG.SYS Ditto. We've got THAT covered in the C:\ directory
already, right?
Now it's time for OUR batch file. Make sure you're currently in the
C:\DOS subdirectory, by saying:
CD\DOS and then put the Tony disk disk in A: COPY A:S.BAT
and now, let's take a look at it:
TYPE S.BAT
Here's how it should look:
echo off
cls
C:
cd\symphony
if '%1'=='other' goto other
symphony
goto end
:other
access
:end
cls
cd\dos
type menu.txt
If we use this batch file, it's a LOT easier getting into
Symphony and its peripheral programs. We COULD make the batch file
simpler by running the Symphony program itself from ACCESS as well, but
that hogs up memory (about 5k, last I heard).
As usual, here are the new concepts not covered before:
SYMPHONY is the "bare-bones", most memory-efficient way of
starting up the main program.
ACCESS is the "shell" to run all of the auxiliary Symphony
programs, as well as the main program itself if you
don't mind the extra memory being used up.
2.2.8.1.1 THE KEY TO A SUCCESSFUL SOFTWARE INSTALLATION.
Here is a VERY important concept I don't want you to miss... After
the SYMPHONY command is invoked within S.BAT, the batch file STOPS. As
soon as we exit from Symphony, the batch file CONTINUES with the next
line! Many people don't get that until they see it happening. This is
THE KEY to designing a batch file to work with ANY software.
2.2.8.1.2 BREAD-AND-BUTTER BATCH FILE & SOFTWARE INSTALLATION.
Here's another, less ornate throwaway example. This procedure is
the SAME for nearly EVERY program out there! Assuming you're in the
mood to install CROSSTALK telecommunications software in the C:\XTALK
subdirectory, here is the QUICK way to do it.
MD\XTALK
CD\XTALK and put the Crosstalk program disk in A:
COPY A:*.*
ERASE COMMAND.*
CD\DOS
Then, I'd create a batch file called XTALK.BAT that would look like
THIS:
echo off
cls
C:
cd\xtalk
xtalk
cls
cd\dos
type menu.txt
Then, using EDIX to modify MENU.TXT, I'd add a line that looks like
this (the line referring to "xtalk"):
╔══════╦═════════════════════════════════════════════════════════════╦══════╗
║ MENU ║ Type one of the below and then press Enter. ║ MENU ║
╠══════╩═════════════════════════════════════════════════════════════╩══════╣
║ menu - To see this menu again. ( menu 2 - for second menu) ║
║ s - For Symphony (s other - for Tutorial, PrintGraph, etc.) ║
║ xtalk - For Crosstalk XVI. ║
║ ║
║ lockup - To SAFELY TRANSPORT this computer from place to place. ║
║ f - To FORMAT a floppy disk in drive a: ║
║ dos - To INSTALL DOS on a freshly formatted diskette. ║
║ fastcopy - To make a perfect COPY of a floppy disk. ║
║ fullback - To back up ALL of the information on the hard disk. ║
║ endofday - To back-up TODAYS information from the hard disk... ║
╚═══════════════════════════════════════════════════════════════════════════╝
That's the big point this whole article was leading towards! If that
seems a little too easy, I wouldn't be surprised. Too many people
OVERCOMPLICATE life for themselves and their friends. It CAN be simple!
I've found that batch files that look like this are my batch file
bread and butter. A good 90% of the batch files that I've created to
begin using TIM IV or Multimate or other software look just like this
one, with only the 4th and 5th lines being different from file to file.
Again, if you follow the simple guidelines I've set out in this
article, you can add in just about any new software just by creating a
new subdirectory, copying the diskette into it, and creating a batch
file in the C:\DOS directory that follows the above guidelines.
2.2.8.2 THE LOCKUP.BAT FILE.
USING THE SHIPDISK COMMAND... (for IBM-brand hard disks)
Take out the reddish-colored "Guide to Operations" book that
came with your computer, and open it to the inside back cover. You'll
notice that there is a diskette there, labeled "Diagnostics". Put that
disk in drive A: and issue the following command:
COPY A:SHIPDISK.*
This copies any files present on drive A: with names that begin
with "SHIPDISK" onto the current disk drive and directory. (Hopefully
still the C:\DOS subdirectory of drive C:)
Then, let's put the Tony disk in A: and say
COPY A:LOCKUP.BAT
Here's what LOCKUP.BAT looks like:
echo off
cls
C:
cd\dos
echo This routine is about to "Lock Up" the
echo computer's hard disk, making it
echo SAFE to move from place to place.
echo Do you want to continue?
query
if not errorlevel 1 goto no
cls
echo Wait for the red light to go off
echo before doing anything else...
echo In order to get the hard disk to work
echo at all from now on, it will be
echo necessary to turn off the computer
echo and then start it up again...
shipdisk
:no
cls
type menu.txt
Here's the reason for this batch file: When you physically move
an IBM hard disk, it's important to do some preparation. The hard disk
reads information with an "arm". If that arm bashes against some
information on the disk, it might cause some damage in an unpredictable
way.
Therefore, IBM has provided a "shipdisk" command on the
"Diagnostics" disk that tells the hard disk's arm to move to a safe area
on the disk and stay there.
2.2.8.3 THE F.BAT FILE.
This batch file is designed to SAFELY format two different types of floppy
diskettes. The HIGH density disks (1.2 megabytes) and the LOW density disks
(360 kilobytes). This batch file is designed for a computer that can HANDLE
these two different types of diskettes. If you have an OLDER type of computer
that can only handle the LOW density diskettes, look further for the proper
batch file.
To use this batch file, you would type
F if you want to format a LOW density diskette.
F HI if you want to format a HIGH density diskette.
echo off
cls
c:
cd\dos
if '%1'=='hi' goto HIGH
if '%1'=='HI' goto HIGH
echo You are about to format a 360k floppy disk in drive a:
echo This will wipe out all information (if any) that exists on
echo the disk. Do you want to continue?
query
if not errorlevel 1 goto end
format a:/4
goto end
:HIGH
echo You are about to format a 1.2 Megabyte (HI-CAPACITY) floppy disk in drive a:
echo This will wipe out all information (if any) that exists on
echo the disk. Do you want to continue?
query
if not errorlevel 1 goto end
cls
format a:
:end
cls
CD\dos
type menu.txt
If you have an OLDER type of computer that can only handle the LOW density
diskettes, here is YOUR F.BAT file:
echo off
cls
c:
cd\dos
echo You are about to format a floppy disk in drive a:
echo This will wipe out all information (if any) that exists on
echo the disk. Do you want to continue?
query
if not errorlevel 1 goto no
format a:
:no
cls
type menu.txt
2.2.8.4 THE DOS.BAT FILE.
echo off
cls
c:
cd\dos
echo You are about to install the Disk Operating System on a floppy disk
echo in drive a:
echo This makes the floppy diskette have the power to start up the
echo computer all by itself, before any hard disk gets a chance to do so. If
echo you're using a hard-disk-equipped machine, you won't normally be needing to
echo do this procedure, because you'll be starting up the computer using the
echo hard disk most of the time.
echo Again, this is normally NOT NECESSARY for most diskettes, and it hogs
echo too much storage space. Do you want to continue?
query
if not errorlevel 1 goto no
cls
echo Please make SURE you have a diskette in drive a:!!!
pause
cls
echo Presently transferring the first two invisible system files. . .
echo These files are called IBMDOS.COM and IBMBIOS.COM, and they are
echo ONLY necessary on a diskette if you intend to start up a computer
echo with that diskette.
echo
sys a:
echo . Copying the third file over. . . (COMMAND.COM)
copy c:\command.com a:
:no
cls
type menu.txt
Here's the explanation for the new commands in this batch file:
SYS A: means that we want to copy two of the
previously-mentioned hidden
files onto our new floppy disk, so that it will have 2/3 of the ability
to start up the computer if we want it to.
(Remember when we got a display of the total disk space and electronic
memory? You were told that there were 3 hidden files. The third one was
the file where the name is stored).
"copy command.com A:" gives the floppy disk the last 1/3 of the
above-mentioned ability, by putting a copy of the DOS file "command.com" on
drive A:
As of now, that floppy disk can start up a computer like yours with
no error messages. However, this whole batch file is not used very much,
because those three files (the two hidden files called IBMDOS.COM and
IBMBIO.COM, plus good old command.com) take up about forty or seventy thousand
characters of space on a floppy disk, which might well be used for other
things, like backup copies of all of your personal letters and phone lists.
In other words, don't use DOS unless you know for a fact that the
diskette will be starting up somebody's computer on a regular basis. Probably
95% of the floppy disks you'll deal with on a regular basis will only hold
stuff important to human beings, not to computers.
Let's go on:
2.2.8.5 THE FASTCOPY.BAT FILE.
echo off
cls
C:
cd\dos
echo You are about to make a quick copy
echo of a floppy disk in drive A:
echo onto another disk (later on) in drive A:
echo Do you want to continue?
query
if not errorlevel 1 goto no
diskcopy A: A:
:no
cls
type menu.txt
ECHO You are etc. is an authorized exception to the "zip your lip"
command. We WANT a message to be flashed on the
screen, and the echo command can do it for us.
DISKCOPY means to make a perfect copy of one
diskette in its entirety onto another diskette.
There is no batch file here for the "diskcomp" command, which
verifies that our diskcopy was okay. This is because we said "verify on" in
our autoexec.bat file when we started up the computer.
2.2.8.6 THE SLOWCOPY.BAT FILE.
echo off
cls
c:
cd\dos
echo You are about to make a slow (but PERFECT)
echo copy of one floppy disk in drive a:
echo (the SOURCE diskette) onto another diskette (The TARGET disk).
echo Do you want to continue?
query
if not errorlevel 1 goto no
copyiipc a: a:/v
:no
cls
type menu.txt
2.2.9 BACKING-UP THE HARD DISK.
I DID NOT COMPLETELY originate the following three files: BACKUP.BAS,
FULLBACK.BAT, and ENDOFDAY.BAT. These were heavily modified from a
wonderful article in a past issue of the PC-oriented magazines. If I can
find out who the original author was, I'll be glad to give them credit.
Here's a hot tip from Tony to you... since the DOS manual doesn't go
into great detail to tell you, here is the proper procedure for
COMPLETELY backing-up all of the information from the hard disk onto
some floppy diskettes. The reason why we want to do this is because
we've already created a carefully-constructed collection of valuable
information, and we're fully aware that accidents can happen. We want
to be able to keep an emergency copy of all of our subdirectories,
software, utilities and hard work. I'll explain how to do the
dumping-back procedure later.
Here is the way my backing-up procedure works: If you want to perform
a COMPLETE backup of everything on the hard disk, you would invoke the
FULLBACK
command. This would give you some advice about how to be prepared. Once
you begin the backup procedure, you'll get asked for each backup diskette
in turn.
Let's say it takes you 17 diskettes to completely backup your hard disk.
If this were true, then 16 diskettes were COMPLETELY filled, and probably
diskette # 17 has some empty space left. We WILL be using this empty
space!
The BACKUP command copies each file onto the diskettes, and making a
little notation in the hard disk's directory by each file's name,
indicating the file has been backed-up. For the sake of being simplistic,
I'll call this notation a "chalk-mark". Later on, if you modify any files
by adding names to your database or re-saving a worksheet or copying a new
file onto the disk, you'll also "erase" the "chalk-mark". This is why the
ENDOFDAY batch file exists. I'll refer to it shortly.
After the FULLBACK command gets through with backing-up onto floppy
diskettes, it'll beep and ask you what diskette you have in drive A:
Using our example, let's say you open the diskette drive door and take a
look at the diskette, which is labeled "BACKUP #17". You type in
17
and press enter, and that information is stored away for later use by the
ENDOFDAY batch file.
So, you continue using your computer over the next week, adding new
information. It's time to do an ENDOFDAY backup!
Let's pretend once again that diskette # 17 still has some room left on
it. If you give the
ENDOFDAY
command, it searches though the entire hard disk, looking for any files
lacking a "chalk-mark". If it finds them, it adds them onto disk # 17,
continuing to fill it up. If disk # 17 gets filled up, you'll be asked for
disk # 18 and so on. You might want to do this sort of thing every week,
and at the end of the month, do another FULLBACK on a completely different
set of diskettes. At the end of the NEXT month, RE-USE the original backup
diskettes with another FULLBACK procedure. This is the safest way of doing
a backup of your hard disk, if you're using the DOS BACKUP.COM command!
2.2.9.1 THE FULLBACK.BAT BATCH FILE.
echo off
cls
c:
cd\dos
echo You are about to begin the process of COMPLETELY backing-up the
echo information stored on the hard disk...
echo
echo Every step will be explained to you as you go through this procedure.
echo
echo If you're new to all of this, here's what you should do. In order to continue
echo this procedure, you should have AT LEAST fifteen formatted diskettes ready.
echo The average 10 megabyte hard disk holds a maximum of 30 diskettes worth
echo of information.
echo
echo If you don't have enough diskettes ready, just answer "n" to bomb out of this
echo part and go buy enough diskettes to get the job done. Then format the
echo diskettes.
echo
echo Then, put a paper label on each diskette, and give each one a label like
echo Backup disk 01,
echo Backup disk 02, etc.
echo and then give the FULLBACK command another try.
echo
echo If you've done a FULLBACK backup before, just re-use the old backup disks.
echo
echo Are you FULLY prepared to continue?
query
cls
if not errorlevel 1 goto end
backup c:\ a:/s
echo This pause is intended to let you see if there are any messages from DOS.
pause
cls
if errorlevel 4 goto failure
if errorlevel 3 goto you-stop
if exist \dos\*.msg erase \dos\*.msg
basica backup
cls
echo Hurray! judging from the lack of error messages from DOS, It worked properly!
echo Okay... You're all done! Now, take all of your backup disks
echo and HIDE THEM UNDER THE BED!
pause
goto end
:you-stop
echo Evidently you told the computer to stop by pressing Control-Break...
echo That's fine, but PLEASE do another backup as SOON as possible!
rebeep
goto end
:failure
echo WARNING! WARNING! WARNING! WARNING! WARNING! WARNING! WARNING! WARNING!
echo Oh, no! This computer is acting up! The backing-up procedure is
echo in desperate need of being re-run!
echo WARNING! WARNING! WARNING! WARNING! WARNING! WARNING! WARNING! WARNING!
rebeep
:end
cls
cd\dos
type menu.txt
This batch file takes advantage of the fact that the BACKUP.COM file
sets an errorlevel according to how well things went during the backup
procedure. I included these lines:
if errorlevel 4 goto failure
if errorlevel 3 goto you-stop
because I've had personal experience where the BACKUP command did NOT
completely backup all of the hard disk due to a wiped-out floppy diskette.
The FULLBACK batch file will alert you if something major goes wrong.
Please refer back to the section explaining the QUERY command for more on
errorlevels.
2.2.9.2 THE BACKUP.BAS FILE.
I also refer to "basica backup". This is the ONLY time I use the BASICA
language.

The other text file created by BACKUP.BAS is called BACKUP.MSG, which
contains the name/number of the last diskette used for a backup:

IN CLOSING:
I've worked like a slave on this article, and I've asked about 20
people to go over it and give me stern criticism. That was about 3 weeks
ago. Since then, two have done so. I'm strongly desiring to get this
article out onto the bulletin boards, so I'm going to ask you once again
to contact me if something is left open to doubt or needs further
clarification. I'm honing my writing skills, and I want to continue
putting out the information I've gathered. I have enough RIGHT now for
about 17 articles of this length, and I'm still gathering.
Drop me a line!

2.3.3 SUGGESTED READING.
(All recommendations are my own opinions, formed after personal experience)
Recommended reading material for beginning computer learners:
PC World magazine. I've noticed that their emphasis has been on getting the
"big picture", and they can sum up a lot of information in a few pages in a
way that a beginner can understand.
Recommended reading material for intermediate computer learners:
PC magazine (The independent guide to IBM Personal Computers). A
twice-weekly magazine, containing wonderful pearls amidst the endless
advertisements. For example: the Departments section of the table of
contents shows the page numbers of the "User-To-User" and "PC Tutor"
columns, which educated me more than any other source, along with the
corresponding columns in PC World magazine. Great for finding out the
stuff that IBM never told you.

Recommended reading material for people who are ready to dive into the
deep end:
Inside the IBM PC by Peter Norton.
An excellent book, but easier to understand if you pay extra for the
diskettes that are offered as supplements to the book.
