Way cool! If you want me to test out the patch, I'd be happy to. Funny, I thought 5.8.0 had made it out the door.

To break at a loop % statement part way through the loop, use conditional breakpoints. Aaagh! Oomph! *blink* That sure flew by as it knocked me over. Time to tape those 5 lines to the top of my monitor and go back to the doc for the debugger... :-) % % -- % Peter Scott % Pacific Systems Design Technologies % http://www.perldebugged.com/ Thanks & HAND :-D -- David T-G * It's easier to fight for one's principles (play) [EMAIL PROTECTED] * than to live up to them. -- fortune cookie (work) [EMAIL PROTECTED] http://www.justpickone.org/davidtg/ Shpx gur Pbzzhavpngvbaf Qrprapl Npg!
