I cannot think of one rational or even irrational reason *not* to use
global variables.  Can you explain this to us?

Do yourself a favor, declare and global like:
		char	*progname;

and the first line in your program do:
		progname = argv[0];

and save yourself a lot of unnecessary problem--including the waste in
CPU time and disk access trying to read the proc table for something
that is just handed to you.  Then again, if you are running a Cray... :-)
