Msg 070 is 04 line(s) on 05/06/85 from CLARENCE WILKERSON
to CP/M-86 about CLOCK

On the IBM PC version of CP/M-86, how does one access the clock from
an assembly language program? I want to be able to set it from my AST
6pak+ board. I have the routines to read the AST, but can't find any
documentation on setting the software clock, except via TOD.CMD.
