Yup, the language was indeed PILOT, which was a language focused on CAI (Computer Assisted Instruction). It was written in BASIC (a pretty large series of programs) on the HP Timeshared BASIC system. It was used quite a bit in the Chemistry and Math curriculums at the high school I went to run courseware for these classes. It annoyed us computer guys, as it meant more kids coming in to compete for the online 33ASR TTYs! Rick Bensene The Old Calculator Museum http://oldcalculatormuseum.com
