Declare main as such:

int	main( int argc, char *argv[] )

Then argv[0] is the pathname of the executable, eg
"C:/PROGRAMS/HTML/HTMLED.EXE"

Simply search backwards from the end of the string until you find a '/' and
replace it with a 0 (null), to signal the end of the string. I have a
routine that I automatically include if you would like it.

Note that the use of '/' is DJGPP specific (I think) - most other compilers
would require a '\\' (escape sequence for a backslash) as it is the DOS
standard.
