Re: Passing arguments to functions.

What is a "function module"? An example of what $command actually contains would help.

I recommend passing a code reference as first argument, this is the most generic way to solve this kind of problem.

use 5.010;
use strictures;

sub execute_command {
    my ($code, $params) = @_;
    say 'Inside executeCommand';
    say 'Currently executing: ', ref $code;
    foreach my $element (@{ $params }) {
        say "Parameter: $element";
        $code->($element);
    }
}

my $command = sub {
    # I am going to print the arguments I receive!
    say @_;
};

execute_command($command, \@paramlist);

Hi, Thanks for your reply, i will try your approach and let you know the results. $command is a normal perl function , it might do anything as you defined it can just print the passed arguments as well. In my case $command is a value got by parsing an xml which is a name of a function.. $command = launchapp; launchapp is the function name which needs to be triggered.	[reply]
