Memory space in a computer — regardless of how much you have plugged in — is allocated for certain jobs. Two major sections of memory that concern ZX PRO/FILE are the program area of memory and the variables area. When PRO/FILE runs, all files are stored in the variables area. With 16K attached, the files

Some people report bugs in ZX PRO/FILE such as report-4 (out of memory) errors, report-5 (not enough room on screen) errors, and during SAVEs, some report that the computer goes ape. All problems exhibit a shocking degree of non-uniformity except for one thing: 16K Memotech RAM packs were used in every case. I have tested
At this point, let’s give credit where credit is due. As you may know, SRAM HI*RES Extended BASIC is a collection of new commands that make use of a high-res core routine developed by Mr. Wilf Rigter.
