 jl> I tried this on Warp4 but it returned 87.

Here is some working code:

 // from my Colos2/95 presentation.
 #define INCL_NOPMAPI
 #define INCL_DOS
 #include 
 #include 


 /* definitions for DosDumpProcess */
 #define DDP_DISABLEPROCDUMP  0   /* disable process dumps */
 #define DDP_ENABLEPROCDUMP   1   /* enable process dumps */
 #define DDP_PERFORMPROCDUMP  2   /* perform process dump */

 APIRET  APIENTRY DosDumpProcess(ULONG Flag, ULONG Drive, PID Pid);

 #define ORD_DOS32DUMPPROCESS            113


 int main(void)
 {
     APIRET rc;
     char *null = NULL;

     rc = DosDumpProcess(DDP_ENABLEPROCDUMP, 'C', 0);
     if(rc)
         printf("sys%04u: DosDumpProcess() failed\n", rc);

     *null = 0;  // cause a trap.
     return 0;
 }
