CP/M 3

This archive contains an almost complete build of CP/M 3.

If you have the source distribution, the file MAKING.DOC explains how to set up the build environment on your computer.

Differences from Digital Research CP/M 3

All the CP/M 3 patches described in the document CPM3FIX.PAT have been applied to the source code, except those to INITDIR. Patches 1-18 (except nos. 5 and 9) were applied.

CP/M 3 is now fully Year 2000 compliant. This affects the programs DATE.COM, DIR.COM and SHOW.COM.

Dates can be displayed in US, UK or Year-Month-Day format. This is set by SETDEF:

  SETDEF [US]
  SETDEF [UK]
  SETDEF [YMD]  respectively.

The CCP has a further bug fix: A command sequence such as:

C1 :C2 :C3

will now not execute the command C3 if the command C1 failed.

What's missing?

INITDIR.COM - because it is written in PL/I and I can't make the PL/I compiler at http://cdl.uta.edu/cpm compile it. Apparently a more recent version of the compiler is required.
