I'm assuming that the use BigLevers; statement has exported it's variables into your namespace using the standard Exporter mechanisms. In that case, the exported variables will now have entries in your current package's typeglobs.

Assuming thatyou're working from the main package, you can do something liek this to find out which variables have been exported to your package:

if (defined *{$main::{NETOVERGROSS_ORDS}}{SCALAR}) {
  # $NETOVERGROSS_ORDS exists
} else {
  # $NETOVERGROSS_ORDS doesn't exist.
}

If messing about in typeglobs doesn't thrill you, then you can use the Devel::Symdump module which will do it all for you.
