Finding where an executable was run from -- a proposal.

   From: "David Korn[eww]" <dgk at ulysses.homer.nj.att.com>

   ksh passes the full pathname of the executable as the first environment
   variable and names it _.  Thus, if the program is run by ksh,
   genenv("_"); returns a pathname for the executable.  Now if everyone
   would follow this convention the problem would be solved.

Everyone won't, especially the hackers who want to fake it out.

BTW, if you are interested in how to make ksh portable, take a look at
how GNU emacs is done. I didn't say it was pretty, but using cpp to
build a makefile for you might be a win.
