Editorial

I am the proud owner of a TRS-80 Model II and when I was teaching, I purchased many Model I IIIs and have steered others to the Color Computer. I have probably been responsible for the sale of at least fifty computers. In fact, I have enough faith in Tandy to have invested in their stock. Their performance in the market has been outstanding. I was able to parlay twenty shares into a complete Model II with expansion drives and still have ten shares left over after all of its splits. So, what...

DOES STRING COMPRESSION HAVE YOU TIED UP IN KNOTS TRASHMAN is a machine language utility for the TRS-80 Models I and III. It was written by Glenn tesler, the author of FASTER, and can reduce BASIC'S string compression time by 95 (see table below). When a BASIC program changes a string (words, names, descriptions), it moves it to a new place in memory, and leaves a hole in the old place. Eventually, all available memory gets used up and BASIC has to push the strings together to free up some...

The Snappware College Educated Garbage Collector SNAPP-VI is an intelligent processing function which greatly improves performance of typical BASIC applications. And here's why. Microsoft uses a 'variable length string' in the BASIC interpreter. Each time the string is assigned a new value, it is relocated in a string pool. Periodically the string pool must be reorganized and condensed into a single contiguous area. Performing this string space reclamation is time consuming and inefficient...
