Re: Making variables visible between calls.

How about just this?

my $function = sub {
    my $var = 'xpto'; print ">> $var <<\n"
};

$function->();

That doesn't help. I need to let the user define his own function, and give him the possibility to access some pre-defined variables in case he wish to. My only possibility at the moment is to force the user defined function to receive a set of predefined parameters. But that will mess up some things later... But thanks, anyway ;) Alberto Simões	[reply]

It sounds like you realy want to pass it a hash. Then just preload the hash with values that it should have access to. `my $function = sub {my $v = shift; print ">> $v->{var} <<\n" }; my $params = {var => 'exto'}; $function->($params);` [download] ___________ Eric Hodges	[reply] [d/l]
