I also second Vinayak's recommendation: use the intrinsics!

:cseq -c CATOPEN

CSEQ [2.4] - LPS Toolbox [A.04b]            (c) 1995 Lund Performance Solutions

extern int32    CATOPEN (
   void     *formaldesignator,            /* R26 */
   void     *error);                      /* R25 */
                  /* returns catindex in R28 */
   /*  errors:                                                             */
   /*     0 = ok                                                           */
   /*     1 = open failed                                                  */
   /*     2 = could not access file                                        */
   /*     3 = file not a GENCAT file                                       */
   /*    100 = internal error                                              */



However, simple examination of mpe_dce_catopen (in dcexl.hpdce.sys)
shows that the calling sequence is apparently:

   int32 mpe_dce_catopen (void *formaldesignator);
          /* returns -1 in case of error, and (apparently) sets errno */

NOTE: the code looks incorrect, because it doesn't seem to properly return
0 if there was no error!

I.e.: I certainly wouldn't use it instead of the intrinsic!
