Very good to hear William, thanks.  Obviously, the majority of the older 
code I have "out there" was built with the assembler flavor of the time, 
some even with xsm or csm. Much with the OEM asm and lately the 6309 aware 
asm, all on the coco3 except for the current version of the serial mouse sb 
file.

Cheers, Gene
