Hello,
I just read this in a forum and I have never heard of this before. He was
having problems with a variable not holding it's value when calling it from
a sub. He wrote back and said that this is what fixed it. Can anybody
explain this to me? Here's part of his post:
-------------
What I've found is that in order to initialise my static variable I need to
have a BEGIN statement around it:
BEGIN {
my $static = "abc";
sub doit() {
$static = $static x 2;
print( "$static \n" );
}
} # end of BEGIN statement
I hadn't realised that the BEGIN was required and while testing this found
that $static was not being explicitly initalised prior to its first use.
