software via radio

I probably have the right issue somewhere, but it will take me some time to go through them all.... It's BASIC, using a pretty minimal set of commands. You could use things like PRINT, LET, INPUT< FOR, NEXT, etc. What you couldn't use -- directly -- were things like clear screen, which was CLS on a TRS80, HOME on an Apple ][, printing some graphics character on a PET, etc. Or positioning the cursor. Or many other things that were done differently on different machines There was a set of subroutines that you loaded along with your program. The subroutines were machine-specific, and came with the translator tape. I forget the exact details, but maybe GOSUB 110 was clear screen, GOSUB 120 was postion (text) cursor at the location given by the variables X and Y, and so on. Your program -- which was then machine-independant -- started at line 1000 IIRC. So you recorded this machine-independant program from the radio. The first stange in translating it was to get it into your machine. It was basically CUTS 1200 baud tones and format, it was untokenised (of course). You then merged in the machine-dependant subroutines (which were the same for all Basicode programs) and ran the result. On most machines it was somewhat automatic. You loaded the translator (which was in the machine's native format), it loaded in the Basicode-format tape and stuck the subroutines in memory too. -tony
