I'm having some trouble figuring out how to make a reference to a subroutine in an external .pm file.

Right now, I'm doing this :

External file

package settingsGeneral;    
sub printScreen {
    print $_[0];
}

Main

use settingsGeneral;    
my $printScreen = settingsGeneral::printScreen;
&$printScreen("test");

but this result into an error: Can't use string ("1") as a subroutine ref while "strict refs" in use

While it is reading through the file, if some condition is met, then "return" that line and keep processing. I know there are those that will… >>> More
