Im just learning Perl and was a little confused with why I couldnt prevent my subroutines from reading variables from the main program. Here is an example:
use strict;
my $var = 1;
test();
sub test
{
print $var;
}I had thought that a my variable would not be able to be read by the subroutine, but it can still see it. So my question is how can I prevent subroutines from having access to variables in the main program. Thanks for any help,
Dave
