I realize this is a very stupid question to those of you who use perl on a daily basis. Truth of the matter is, I taught myself Perl last week and I'm still learning. I thought this was a place to come and get help, not be ridiculed. If you don't know the answer to my question, why reply? Why beat around the bush? I know that POSIX comes as part of the core distribution and has for at least 3 or 4 releasess. Simple fact is, our Business Server does not have POSIX installed (it is an older version, and was stripped down when installed). Now I know that POSIX.pm is only the front end to POSIX.xs. I haven't been able to find POSIX.xs. Where can I find it? When I do find it, how do I compile it?
