The problem I was trying to convey is that prior to using strict I had to Arrays, @headers and @body. In several subs I access the information in these arrays. Now when I declare these arrays with my they are no longer accessable to my subs. I realize that I could declare them @main::headers and @main::body but thought that since one of the things strict does is help to avoid global variables that I might be better of passing the values to the subs instead of making them global. If this is not correct, then I will just use @main:: If it is, however, then I need some advice on how to get a string and two Arrays passed to a sub. I hope that clears up my question =) Sheridan Saint-Michel -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
