I'd been using prints liberally too, but my sophistication of usage hadn't got much beyond stoneage. I've been using a print clause I can insert by typing an abrev that gives me a starter `print "hpdb _\n";' And where you see the underscore is where my cursor would land when I typed the abrev `hpd<spc>'. I thought I was really getting with it... hehe. What you posted is like the difference between a manual clutch, and torque converter. And then controlling if with a cmdline switch... alright.. now were talking. -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
