By the way, is there a filing system equivalent of *FX142, ie to
change FS without typing in the usual start-up command?

Best wishes,


Ian

You get that if you miss out the "P" from the filing system name. The Master 
MOS understands "-CFS-" as an alternative to "-TAPE-" (short for "Cassette 
Filing System" I believe).

You might just also get it from having duplicate filing system ID numbers. 
Use *OPT 7 in CPFS to set the Filing System ID to something unique. The 
default is 5 (same as *NET - the documentation explains why), but you can 
change it to whatever you like and it is preserved in the Master's CMOS 
memory so you don't need to repeat it once changed.

(*MOVE works perfectly well with CPFS, but it is limiting because it only 
allows you to copy one file at a time. That is why I included the command 
*TRANSFER in the CPFS ROM.)
