Dick:
An admirable opportunity for you to get into some program adaptation.
All you will need to do to take advantage of the Tandy 200's larger screen is
make judicious use of the PRINT@ statement. Don't know if Roger used them on
his program [haven't looked], but break out your Basic 200 Manual and work on
that statement a bit.
If you use PRETTY to give you a hard copy listing of the programs you
wish to adapt, it'll be a LOT faster and easier. Oops! Can't use PRETTY, okay
then get LEGIBL.BA from DL7 or LISTER.100 from DL4.
As to the OS error; you are operating with less RAM than most Model 100
folks have, and that could be the problem. Check the initializing of SCHDUL; it
most likely has CLEAR 500 or some such in an early line, increase the value
cleared and see if you get along better.
Doubt if Roger is active any more …
Lotza luck …
