Compusa Disk Fix

I, too, have a Compusa Disk system for my TS 1500. I use a different method to save to disk which allows me to save to tape if I want to. The method described in Updates 1:3 forces you to delete old data BEFORE you save the new data. That practice could lead to disaster.

I dedicate a disk to my expanded (D$=30002) version of ZX Pro/File. I use preprogrammed functions to enable my drives when I want to save “ZX”. I number the programs increments of .01, which allows you to re-save the program (after additions or changes) without first deleting the old. I continue like this until the disk is full, then I again use the preprogrammed function to delete those old version (except the last 2). Now I can continue using the same disk over and over.

I wrote 2 programs (one to save to disk, one to delete old version), both are accessed by the “DO-FILE” method described on page 43 of the Pro/File Manual. Listings are shown below.
