Perl has no built-in switch statement. The Switch module should not be used. As you don't show any code and don't show what problem you are trying to solve, I can't help you further.

You might want to read some warnings on using Switch:

i WAS THINKING OF USING IT IN A RPG IM WORKING ON, WELL IT'S A PROJECT I USING TO LEARN PERL. I WAS GOING TO USE THE SWITCH MODULE FOR THINGS LIKE MOVEMENT. ROUGH EXAMPLE CODE NOT TESTED.

USE SWITCH;
SUB DIRECTIONS {
WHILE {
$DIRECTIONS= (<STDIN>);
    CHOMP $DIRECTIONS
    $DIRECTIONS =~ TR/A-Z/a-z/;
    SWITCH {
        CASE 'NORTH'    {PRINT "$HERONAME HAS LEFT NORTH"}
        CASE 'SOUTH'     {PRINT "$HERONAME HAS LEFT SOUTH"}
        CASE 'EAST'      {PRINT "$HERONAME HAS LEFT EAST"}
        CASE 'WEST'      {PRINT "$HERONAME HAS LEFT WEST"}
        }
    }
}

BASICALY THATS WHAY IM TRYING TO DO...BASICALY

Just use several if statements:

if ($DIRECTIONS eq 'NORTH') { print "$HERONAME HAS LEFT NORTH\n" }
elsif ($DIRECTIONS eq 'SOUTH') { print "$HERONAME HAS LEFT SOUTH\n" }
elsif ($DIRECTIONS eq 'EAST') { print "$HERONAME HAS LEFT EAST\n" }
elsif ($DIRECTIONS eq 'WEST') { print "$HERONAME HAS LEFT WEST\n" }

Sounds like you just need to use dispatching. i.e. make a hash which contains the possible commands/directions as keys, and has strings to output as values. (Or probably more useful, has coderefs as values to be run)

Your best bet is to avoid using Switch at all, especially in production code. It is very easy to introduce very hard to trace bugs and is just too fragile.

If you have a large number of possible branches use a dispatch table, otherwise, if-then-else (or ? : ).
