in reply to Re^2: prob w/ gatekeeper subroutine
in thread prob w/ gatekeeper subroutine

I use them as global variables and a global hash so that the subroutines permanently change them.

Don't do that. It's called action at a distance and it's considered a bad practice. Instead of modifying a global variable, you should return a value from entersys().
