| # Alternatively, you could check for validity this way:
| #  :0
| #  * ! USERNUMBER=^^(some regexp to check for currently valid numbers)^^
| #  routine_for_invalid_numbers

Oops!

# Alternatively, you could check for validity this way:
#  :0
#  * ! USERNUMBER ?? ^^(some regexp to check for currently valid numbers)^^
#  routine_for_invalid_numbers
