}How do you make MacPerl evaluate an operator placed in a scalar? For example,

}if ($num1 $op $num2)
}{
}...

Use eval.  This seems to work correctly for various $op's:

#!perl

$op = ">";
$num1 = 10;
$num2 = 2;
if(eval "$num1 $op $num2") {
 print "is\n";
} else {
 print "isn\'t\n";
}

}
}Many thanks.
