Re: Scope of a Hash

in reply to Scope of a Hash

I call a subroutine &createExcelChart that passes the hash in as *returnVals.

AAaaah !!! Why do you do this ??
Don't use typeglobs to pass variables around !
It's illegal ! It's punished by The Law (tm) ! It will not work with use strict !

If you want to pass a hash to a function you should use a reference to the hash, i.e :

my %hash = ( 'some' => 'things' ) ; callFunction( \%hash ) ;
In the function you can for example dereference the hash :
sub callFunction { my $refhash = shift ; my %hash = %$refhash ; ... }

    It will not work with use strict!

    It won't? Coulda fooled me.

    use strict; use warnings; sub foo { our $bar; $bar = "Hi"; return *bar; } my $foo = foo(); print $$foo, "\n"; __OUTPUT__ Hi

    Not that I disagree with the rest of your post, though. This type of thing is odd, but it's not disallowed by strict by any means.
