ShowComment.rexx 1.03
© 1995 Felix Coronado
------------------------
ARexx program to display JPEG and GIF file comments
------------------------
Copyright and Distribution
==========================
ShowComment.rexx is copyright 1995 by Felix Coronado. All rights
reserved.
ShowComment.rexx is Freeware and it may be distributed only if:
1. it is in its original unmodified form
2. it is accompanied by this documentation
3. nothing is charged for it, other than the cost of the media and nominal
duplication fees
Any distribution of ShowComment.rexx that does not meet all of the above
requirements must have the prior written permission of the author (Felix C.
Coronado).
Permission is granted to include ShowComment.rexx in Fred Fish's Amiga Disk

Disclaimer
==========
This program (ShowComment.rexx) comes with no warranty, either expressed or
implied. The author (Felix Coronado) is in no way responsible for any
damage, loss, or ill-effects directly or indirectly caused by the usage of
this program.
------------------------
What Does It Do?
===============
ShowComment.rexx is an ARexx program that searches for and displays any text
comments contained in a JPEG or GIF file.
NOTE: ShowComment.rexx will only search for comments in JFIF JPEG files, as
this is the only type of JPEG file that it was designed to recognize. This
limitation is due to the fact that I have no information on the other
varieties (HSI JPEGs, TIFF JPEGs, PICT JPEGs, & others?) of JPEGs. I don't
even know if they can contain comments.
------------------------
Requirements
============
ARexx
------------------------
Installation
============
Copy ShowComment.rexx to your S: directory or elsewhere.
------------------------
Using it
========
ShowComment.rexx should be run from the Shell/CLI. Its usage is as follows:
RX ShowComment.rexx <filename>
or if its "s" protection bit is set:
ShowComment.rexx <filename>
where <filename> is the complete path and filename of a JPEG or GIF file.
Once it starts, ShowComment.rexx will display:
ShowComment 1.03 - Copyright (c) 1995 by Felix Coronado
If the file you pick is a JPEG or GIF file, ShowComment.rexx will then
display the following:
Searching for comments in '<filename>'...
Ctrl-d to stop
ShowComment.rexx is now searching the selected file for comments. If you
press Ctrl-d (the "Ctrl" key and the "d" key at the same time) while "Ctrl-d
to stop" is displayed, ShowComment.rexx will stop searching for comments.
Pressing Ctrl-c while "Ctrl-d to stop" is displayed will abort the program.
If you stop the search before any comments are found, or if no comments are
found, ShowComment.rexx will display the words "No Comment".
If ShowComment.rexx is able to find comments, it will display the following:
Comment <number>: <Comment>

Contacting the Author
=====================
If you have any bug reports, questions, suggestions, comments, or gifts to
send me or if you would like information about the most recent versions of
my programs, I would be glad to hear from you. I would particularly like to
hear from you if:
1. You come across a JPEG or GIF file that you know contains comments but
ShowComment.rexx does not recognize it or does not display the comments.
If this occurs, I would appreciate it if you sent me a copy of the file so
that I could try to fix the problem.
2. You have any information relating to:
a. JPEG and GIF file comments (programs that let you add/edit them, etc.)
b. the various JPEG file formats (the structure of JPEG files, what JPEG
file formats contain comments, etc.)
