INTRODUCTION - by Andy Lusher




Jim Hamilton handed me a disk in 1982 that changed my life forever.
The media contained a copy of Tom Jenning's Fido (tm) BBS software
and I promptly put it to use. Ever since that event, I've been the
sysop of a bulletin board, and I still blame him!


On the other hand, Jim has been programming in Assembler, and now
in 'C'. He's written too many good utilities that I have urged him
to release. Some programs that he wrote as early as 1983 are still
in my path, and I have found no equal for them to this date. Jim's
only problems are that he is modest, and a perfectionist (His home
is full of "unfinished" paintings that people would pay to see).
I'd like to believe that I played a part by pushing him into the
release of this utility (or was it the other way around)?


As a first "release" effort, I found uses for the GIFLIST program
immediately. I have a large number of GIFs (tm) on my BBS system,
and get quite a few uploaded by my users. I had problems managing
these because the resolution and number of colors are not apparent.
Most of the programs out there that "tell" you the resolution are
large and cumbersome because they provide viewing capabilities too.
Jim came to my rescue with this utility.


Jim is a GIF(tm) collector. He has limited space on his hard disk,
and stores these offline on diskettes. Unfortunately, most programs
that index your files do not provide enough information to be useful
so he had a need for this also, which is why it was written.

Remember that this is a first effort, and only a beginning. There
are many planned enhancements for this program if your support is
there.

If you collect GIFs (tm), you may find that GIFLIST can help you.

WHAT THE HECK IS A GIF???





Personal computers today have good-to-excellent graphics capabilities.
With the advent of VGA on IBM compatibles, the Amiga and Atari users
can no-longer thumb their noses and laugh at us. Compuserve (tm), the
biggest BBS I know of, proposed a standard that would allow for the
exchange of graphic images between many different kinds of computers.
Better yet, they offered this standard to the public domain, and the
GIF (tm) was born. GIF is the Compuserve Graphic Interchange Format.
It offers a high degree of machine independance, compression to save
disk space, and much more. Many thousands of graphics, digitized
images, prize winning works of art and utilities support this format,
which is very quickly becoming the most popular on this planet.



PROGRAM REQUIREMENTS




COMPUTER

You must have a computer to run this progam. No other way to do it.
This software was been written for IBM or BIOS-compatible PCs only.
It has been tested on PCs, XTs, ATs, and an extremely fussy 3-Com
network. Chances are very good that it will work on your system if
it fits into any one of these categories.

MEMORY

If you can view a GIF, you should have enough memory to run this.

DISK SPACE

This program will take up roughly 14k of disk space.

OPERATING SYSTEM

This program has been tested under all PC and MS-DOS versions
that begin with the number 3.

PROGRAM OPERATION




USAGE: GIFLIST [d:\path] [?|/?] [/t|/bbs] [/res|/da/dd]

d:\path Drive and path to search.
?, /? or -? Calls the GIFLIST help screen.
/t or -t Terse -name (less ext.) & resolution only.
/bbs or -bbs Format listing for "FILES.BBS" file.
/res or -res Sort by resolution - highest to lowest.
/da or -da Sort by date - ascending.
/dd or -dd Sort by date - descending.

You may combine Terse or BBS with resolution or date options.
You may also use (dash) - instead of (slash) / for all options.
If you have GIFs in the current directory, simply type:

GIFLIST (and press the ENTER key)

You should see:

Optionally, you may provide a path like this:

You should see:

In both cases, GIFLIST displays FILENAME, SIZE, DATE and RESOLUTION.

PROGRAM OPERATION (continuation)



BBS OPTIONS

GIFLIST provides some options to allow you to format a FILES.BBS
listing for Opus (no tm) by Wynn Wagner, and some other (tm)
Bulletin Board Systems. The /BBS option may be combined with the
/Date or /RESolution options to allow for greater flexibility.

GIFLIST /BBS will display the following:

GIF Listing Utility 1.0 Copyright (C) 1989 James Hamilton
Distributed by the Code Conjurers OPUS: (613) 224-4480

Volume ... [NO LABEL] 01/01/89 - 20:28:49
Path ..... K:\GIF\640X400

BREAST.GIF 640 x 400 x 256 ** No Description **
EMILYA.GIF 512 x 400 x 256 ** No Description **
FANTASIA.GIF 640 x 400 x 16 ** No Description **
INDIA1.GIF 512 x 400 x 256 ** No Description **
PIRATE.GIF 640 x 400 x 16 ** No Description **
SHARRY.GIF 512 x 400 x 256 ** No Description **
SHAWNA.GIF 640 x 400 x 16 ** No Description **

Total .GIF files found: 7

Note that GIFLIST drops the SIZE and DATE fields, as these are
usually handled by the BBS software, and displays RESOLUTION
and a temporary "NO DESCRIPTION" field for you.

Now, if you are like me, you'll shelve the documentation, and
promptly forget what you need to know. Like many programs, you
can get help by typing:

GIFLIST ? -or- GIFLIST /?

GIFLIST will display a help screen to remind you how to use it.

Also you may get tired of typing GIFLIST all the time. I have
renamed it to GL, and you may wish to do the same.

REN GIFLIST.EXE GL.EXE

GIFLIST will know that you have renamed it, and adjust the help
screen accordingly.

DOS REDIRECTION




What we've covered so far displays on the screen only, but suppose
we need to create a file? DOS provides some useful tools for doing
this, and your DOS manual is the best place to start. Here are some
examples of Standard DOS Redirection that you may find useful.


GIFLIST > FOO.LST Creates a new file called FOO.LST

GIFLIST >> FOO.LST Creates a new file called FOO.LST,
or adds to the end, if the file
already exists.

GIFLIST K:\GIF > C:\GIF.CAT Creates a new file called GIF.CAT that
contains a list of GIFs in K:\GIF
directory...

GIFLIST K:\GIF | MORE Pauses each time screen fills up.


DOS REDIRECTION



GIFLIST is a simple utility, but really has a lot of functionality.
The sample below adds to the existing FILES.BBS in C:\GFX a list of
GIFs sorted by resolution. All you must do is add a description for
each file, and you're away. You may combine /BBS with the /DA or /DD
options if you prefer. Although the date field is not shown, the
order will be correct.

GIFLIST C:\GFX /BBS /RES >> C:\GFX\FILES.BBS

The Program Identification notice that appears when you run GIFLIST
will appear on your screen only, and not in the target file. Also,
the Volume, Path and Total labels do NOT appear in column 1, and
will not show as MISSING files when listed on your BBS.

If you wish to run your directory updates from a batchfile, note
that GIFLIST will exit with an ERRORLEVEL of 0 in normal situations
or ERRORLEVEL 1 if it detects an error.
