A lot of CP/M software came with CRC codes so that one could check file integrity after modem transfer. Also an old copy protection scheme was to have a program do a CRC check on itself after being loaded. If PD software developers included these 2 schemes as standards we could be a little more secure that we were getting legitimate copies of these often outstanding (e.g. ARC512) programs. I guess we've forgotten about CRC checks now that modem comm programs are better! -------

For that matter, S-record format includes checksums. I once proposed S-record instead of uuencode/BinHex for executables for that reason, but the proposal seems to have fizzled out. James Jones
