Update: I found a problem with the discs I had in that when I ran the tests I would get this error when I tried to do a LEARN function: *DO_LRN(551): wrong number of subscripts to 't_upper'* Turns out the cure is fairly simple - edit Line 551: *previous_end=t_upper[our_count]* and change to *previous_end=t_upper[*_Ram,_*our_count]* Seems '_Ram,_' was missing. Now the 9100 Learn works as it should - at least so far...sure is a lot faster than the 9010A, I wish I had done this years ago! I've updated my disc (now numbered Rv1.1) and will attempt to upload it once I have access to a desktop PC so I can save the floppy. Any preference in formats?
