From: Don Maslin <donm(a)cts.com> Stull no arguement, just not the question at hand. DOS like CP/M can have any number of user interfaces, size for the moment is unimportant as it GUI vs Command line. You'd like the version I did for laughs that looked a lot like RSTS running the BASIC interface rather than DCL. Yes, I mean the user enviornment is inside basic and the command line would be BASIC. I used LLL BASIC to do it as its available as source and all. So what if CCP {or ZCPR} is nominally 2k, I changed the load point in the BIOS and allowed 8k for that. Is the user interface different? Yes. Is it CP/M, still? Yes.
