IIRC, back in those days such things could be extremely simple, and it's not unthinkable that someone could write one on a plane flight, especially if they had seen something similar before. And 300 instructions would have been very long for such a beast; recall that the basic interpreter itself probably fit in 4k or so, some systems had 1K or memory (or less total), and when toggling things in on a front panel, brevity was definitely a virtue. No flight simulators easter eggs in THOSE days! BillW -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
