Hi Cory,

Try something like:

     PROCEDURE YieldTimeSlice;
          VAR regs  : REGLIST;
     BEGIN
          regs.AX = #1680;
          intrp(#2F,regs,regs)
     END;

Note that I am assuming you are using IBM Pascal/2 to prepare a DOS
application. I am, perhaps, unique among the Pascal programmers in
this echo in that I do not own a copy of Borland or Turbo Pascal, so I
do not know if this will work with a Borland compiler or not. [Fact
is, I wrote this code just now, so I am not absolutely certain it will
work at all. ... :-) ]

You might also need a TSR like SLICE or TAME to answer the interrupt
in a VDM.

Also, I am not sure whether this question belongs in this echo or the
OS2DOS echo.

Regards

Dave
