Due to public demand I would like to integrate a functionality into Arcgsh
(you know - the GEM shell for Arc, Zoo, LHarc etc.) that allows you to
doubleclick on e. g. FOO.ZOO which causes Arcgsh to be executed and
immediately showing the Zoo parameter dialog box with FOO.ZOO already
filled in as the archive name.

However, what I need to know is the complete path of the executing program.
This is neccessary to read (resp. write) the configuration file which is in
the same directory as the program itself. I played around a bit (using TOS
1.4) with shel_read() and shel_find(), but I am not satisfied with the
results:

- Shel_read() works reliably only when the program is called from the
  desktop. When it is called from a shell it may return the name of
  that shell.

- Shel_find() needs to know the program's name in order to find out its
  path. It works alright if I hardcode the program's name, like
	strcpy (buffer, "ARCGSH.PRG");
	shel_find (buffer);
  but will fail if the program is renamed.

Another observation is that loading the resource file always worked with
rsrc_load ("ARCGSH.RSC").

Does someone have a general solution? It would be sufficient to get only
the directory where the program is located - without knowing the program's
name. Even better would be a possibility to retrieve the program's name
also, and the best would be if this could be done without GEM functions.
And yes, of course only legal solutions are useful.
