Make sure you have also added the "SET DJGPP=..." line to your
AUTOEXEC.BAT as well; it's critical for DJGPP programs to find the files
they need.  If you've done all that, and unzipped with the '-d' flag to
recreate the directory structure, it is installed!  Now, write a C
program and follow the instructions in 'readme.1st' to compile it. 
Remember that djgpp is a command-line compiler, not an IDE-based
compiler like Borland and Turbo C.  You can use whatever editor you
prefer to actually edit code, then save it as a .c file and use 'gcc' to
compile it like so:

> gcc -o myprog.exe myprog.c

(Read:  compile 'myprog.c' and produce 'myprog.exe' as output.)

A more complex example of compilation might be:

> gcc -Wall -O -g -o myprog.exe main.c files.c input.c

(Read:  compile 'main.c', 'files.c', and 'input.c', with all warnings
enabled, standard optimization, and debugging support, and produce
'myprog.exe' as output.)

Basically, all compiler options are controlled by switches you give it
on the command line.  Read the documentation for more information on how
this works; since you did install txi360b.zip, just type 'info' to start
up the DJGPP online hypertext browser.  Other DJGPP tools you may
consider getting include GNU Make (v2gnu/mak373b.zip) which allows you
to build complex programs with very simple commands, the DJGPP library
sources (v2/djlsr200.zip) which let you see exactly what goes into each
DJGPP function, and the GNU debugger (v2gnu/gdb412b.zip) which is a
source-level debugging utility.

That said, there _are_ development environments available for DJGPP. 
Download the file 'v2apps/rhideb.zip' for a beta version of a Turbo
Vision-based IDE designed specifically for DJGPP.  For the ultimate in
editing power, you can download and build GNU Emacs, pointers to which
are in the FAQ (type "info faq").

Finally, a prototype DJGPP installer _is_ in the early development
stages, but pretty much all it will do is perform the steps outlined in
'readme.1st' for you.  :)

If you have any problems getting DJGPP to work, _first_ examine the
'readme.1st' file to make sure you followed all the listed steps.  Then,
load the FAQ and do a search for the problem or error message you
encountered.  Then, and only then, post to the newsgroup/mailing list
and we'll do our very best to help you out.  :)
