Re^2: How to call subroutines using variables ?

eval "&$s()";

Oof. Don't do that. It's a lot safer to turn of strict refs instead:

no strict 'refs';
$s->();
use strict;

That should still be treated with care, though. It will run ANY subroutine (even in other packages) that can be reached by name. Using your eval STRING option will run ANY code that happens to be in $s. Like:

$s = "print(); unlink '/etc/passwd'; s";

Use the full package name, if you MUST use symbolic references: `my $ref = "SomePackage::Name::subname"; $ref->(@arguments);` [download] "What should it profit a man, if he should win a flame war, yet lose his cool?"	[reply] [d/l]
