Ideas like this are what make PICLIST worthwhile. Chatter about C vs. ASM is BORING. Sermons about off-topic vs. on-topic are TIRESOME. Tips on writing good code are USEFUL, but ideas for new applications are VALUABLE. They're the main reason many of us still subscribe! -- Mel Evans .....mevans1027KILLspam@spam@aol.com 313-747-7196
