I did say Linux supports ..:) Depending on what you're trying to do, it might be helpful to know. If you are trying to write portable code, then it certainly isn't.
You may have misunderstood what I was trying to say. What I was hoping was that behind the scenes, perl used these manditory schemes, or perhaps there was a magic module that used one subroutine to portably call the manditory scheme, regardless of OS. Sounds like that's not the case. One can always hope...:)
