ferreira: I'm not determining just the home directory, but the exact directory a user has navigated to, to be able to run the procedure noted and have it use the answer file in that directory. It may not even be that users own directory structure they run the procedure from.
Here's another example:
I am calling a routine:
\u\user100\idaho\perl\functions\sort.pl
But I am calling it from:
\u\userabc\calif\files\answer\
I want to enable an option in sort.pl to know the exact location I am in when I invoke it so it looks for an answer file at my location.
(This whole question is brought about because some users don't want to have to type the path to their own answer files.)
btw: Thanks Ikegami for your time.
