Is what I'm hearing you say is that in the PerlRun environment (and I'm guessing the mod_perl environment too), anything that a subroutine uses coming from outside that code must be passed as a parameter like '&sub($paramter)'. Am I correct in this.
Unless you are trying to create a variable that never changes, yes. This is true in all perl code, not just mod_perl. You don't notice the effect in CGI because the interpreter exits. This is a general good practice for programming -- you want subroutines to be independent and have no side effects on variables that are not passed to them. - Perrin
