Stuff that I wrote on the disk sleeve: To use: { Clear a bit of memory. Load FBACK2.EXE anywhere EXEC start,source,dest where start=where you loaded it to. } OR { Clear some memory. RUN"FBACK2.EXE",addr,source,dest } e.g. PCLEAR1:CLEAR200,&H15FF:RUN"FBACK2.EXE",&H1600,1,2 It'll use ALL memory after the prog whether you like it or not. ciaran Umm... basically I think the object of this was to use any memory on a 64 you happened to have handy, whilst being PIC so as you could co-reside it. Not much use on the emulators I know, but who says you do these things to be of use? - kja3@aber.ac.uk
