Re: Determining what library a CL program is called from?

works fine until you purchase another application from another vendor
with the same brilliant idea (and the same prefix).
The point is, that the only reliable way is to have the top program
in the application figure out where it is running from, and then
pass that info down to all its subprograms (passing it to their
subprograms, etc). Everybody down the line now qualify
their calls (and all other references to files, data areas, etc)
with the library name passed down. Should you run into
a name conflict with the top name, you simply rename it (and
only it) to your liking.
