Not quite. CP/M is not a rename of PL/M. PL/M is a derivative of the programming language PL/I and was used in the development of CP/M - it is not an operating system. CP/M-86 was a later development of CP/M that was designed to run on 16-bit Intel processors. CP/M-68K was another branch of

Yes, and on some machines, like the IBM 1800, small numeric constants are stored in a common location, to reduce the size of executable images. So, once you've changed 4 to 5, it means that all programs that get loaded will now use 5 when they meant 4. Usually the generated code has a way to

Fun that I have had with Fortran: 1) Passing an integer constant where a variable was expected, and having that constant modified by the called routine; on an IBM 1800 / TSX, small integer constants were stored in an area shared with the operating system, so it was supremely easy to change the
