All I'm trying to do is use a sub to print out a nested set of arrays. It should be simple, but I can't figure out what I'm doing wrong. The foreach loop works outside of the sub, but not inside the sub, which is odd because the array should be within the scope of the sub.
Here's the code:
#!c:\strawberry\perl\bin\perl.exe -w
displayBoard( );
@test = (
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ],
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ],
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ],
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ],
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ],
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ],
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ],
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ],
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ],
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ],
);
sub displayBoard
{
foreach ( @test )
{
print "@$_\n";
}
}
I would be very grateful if someone would point out the obvious thing I'm not seeing.
Thanks!
