Subj: REPLY TO MSG #4247 (UNDF OP CODES)
Any undefined opcodes would be undefined opcodes in the Intel 80C85 microprocessor. I believe there were a few, but you don't need to know about them. Using undefined opcodes is risky and isn't necessary. There are many subroutines in the M100/102 that the average BASIC programmer doesn't know about. These "hidden powers" have been the focus of 2 good reference books: "Hidden Powers...." and "Inside the Model 100." Alas, both are out of print. using these routines in programs is recommended.
