Ok, this compiled, but I haven't got to the link stage, so...
In play.c around line 930 or so...:
/* put torpedo into the universe */
pcrft->cr_dir[0] = 1.0;
sptort(pcrft->cr_dir,tmpvec);
for (i=0;i<3;++i) {
* ptorp->tp_pstn[i] = ADD(pcrft->cr_pstn[i],
* ptorp->tp_thr[i]=MUL(tmpvec[i],50.));
ptorp->tp_vel[i] = ADD(pcrft->cr_vel[i],MUL(tmpvec[i],10.));
}
etc.etc.
The *'d lines cause a compiler error, of course. I'm not sure what
the author wanted to do, so I replaced the two *'d lines with:
ptorp->tp_pstn[i]=ADD(pcrft->cr_pstn[i],MUL(tmpvec[i],50.));
I know that this ignores ptorp->tp_thr[i]. Maybe it doesn't matter? :-)
What did you do to fix this?

While I still can't link (I don't have the "dbm" routines), the play.c module does compile (I'm using Greenhills 1.8.0 Compiler on a CRDS UNOS (SYSV) machine). Your change above removes the assignment ptorp->tp_thr[i]=MUL(tmpvec[i],50.) If you change the *'d lines to the following, maybe your compiler will work. ptorp->tp_thr[i]=MUL(tmpvec[i],50.); ptorp->tp_pstn[i] = ADD(pcrft->cr_pstn[i], ptorp->tp_thr[i]); -Allan G. Schrum P.S. Does somebody have a SYSV module for the DBM stuff?

Your problem is the line just following those asterisked ones; those two macros result in an ugly assignment statement. Break them apart, and all should be OK.
