The design of the S/38 was original and remarkable. However, it was marred by that horrible language, RPG (Report Program Generator). RPG was based on a plugboard tabulator paradigm.
Our local IBM reps said that IBM refused to release an Assembler for the S/38, keeping the internals a big secret.
- _JamesA_ 11y agoNot sure about the S/38 but IBM i (AS/400) documentation for programming MI (machine interface) is available [1]. I once wrote an XMODEM crc16 routine in MI because I didn't have the C compiler available and I couldn't get RPG to calculate it fast enough to saturate the modem line.
