	Welllll....  I don't really have enough to go on, but I can make
a couple of WAGs (Wild A** Guesses).

	1) Are you running as root or a common user?  (WAG - root)

	2) Are the files you are running in your current directory or
somewhere else?  (WAG - Current directory)

	Try typing this:	./name_of_program

	Instead of this:	name_of_program

	Note the addition of the leading ./ in front of the name.

	If that works, then "." is not in your path.  You can add it there
with the following command:

	export PATH=$PATH:.

	You really DON'T want to do this as root, however.  It leaves you
open to trojan horse attacks, which is why it is not in root's default
path.  In something like Windows or DOS, you don't have a choice and
'.' is inherently always in your path (and checked first) and that's a
contributing factor to the preponderance of virii and trojans in those
environments.
