This may not be needed for ROMs with only LEX files, but it is mandatory for ROMs that include BASIC files, to make sure the chaining/compilation process is correctly done. This is something we discussed in the past, but I can't find the reference right now.

The CMT tool Port Generate Checksum, PTGENC$ described in Step 10 on p.11 of the CMT-71-P01 manual will chain all files that need to be chained.

Oh yes, you're right. Actually, my experience is mainly with the HHP EPROM module, for which I (at the time) had only the ROMCOPY as a tool.
I programmed CMT modules much much later, when I got a CMT programmer and a few modules (yes, I'm one of the 7 :-)
