The first assigns a typeglob to $uid. This can let you access all the symbol table entries named REAL_USER_ID through $uid. It's kind of like a reference, so you have to dereference it to get to the scalar value of $REAL_USER_ID: $uid = *REAL_USER_ID; print "User ID is ", $$uid; If you do it the following way, you're making uid an alias for REAL_USER_ID: *uid = *REAL_USER_ID; print "User ID is ", $uid; In fact, this is what the English module is doing. > Am I right?
