my @numbers = split /\s+/, <>;
for my $width (@numbers) {
my $result = &calculate($width);
print("size = $width amount needed = $result \n");
}
sub calculate {
my $a = $_;
my $value = $a / 12;
my $b = $value * $squareft;
return $b;
}
Here is the results:
Enter Total Square Footage: 1200
Enter widths separated by spaces:
2 3 4

It is pulling the size out nicely, but the value isnt making it into
the sub?? I have tried my $a = $_[0] , a = @_, a = $width and am lost
now.
thanks again
