Hi Michael,
a simple task. I write in my perl-script my $1 ... But I need this up to $4
or more. I select my $1, and my filter makes out of it:
my ($1, $2, $3, $4);
But you are right: this are reserved scalars (blushing) ...
so I change my task to:
my $scalar1,
with filter becomes:
my ($scalar1, $scalar2, $scalar3, $scalar4);
Was this clearer?
best greetings and sorry for the confusion
marek
