It's not really mentioned in the thread so far, but weirdly... PL/I was one of the inspirations for PL/M, which was the basis for CP/M... which was the basis for DOS... which led us to Windows... which leads us to today for those that don't use other OSs, etc, etc.
- timbit42 5y agoPL/I and PL/M are languages. CP/M is an operating system. The '/M' and that CP/M was mostly written in PL/M are the only 'basis' for CP/M from PL/M, but PL/M didn't affect what CP/M was created as.
- hungryforcodes 5y agoWait. You're saying that CP/M was created with PL/M but PL/M didn't affect CP/M?! It's been a long day huh?
- timbit42 5y agoI'm saying PL/M didn't affect the design of CP/M. You could write CP/M in C or assembly and it would be the same.
- hungryforcodes 5y agoOK, I see what you mean. I think actually the BIOS was written in assembly, and you had to customize it for each system you made CP/M for -- so fair point. :)
