That is the same method I used when I had the similar problem: calling a given
XPLINK C routine from PL1.

I wrote a NON-XPLINK C function which called the XPLINK function via fetch (). I
was able to call the NON-XPLINK function from PL/1.

excerpt from the "glue" function:



/**********************************************************/
/*                                                        */
/*   Funktionspointer-Typedef fuer externe Funktion       */
/*                                                        */
/**********************************************************/

typedef int (*funcptr) (char *is,
                        int *ilg,
                        char *os,
                        int *olg,
                        char *key,
                        int *klg);



// in the main function ...


    static funcptr pfunc = NULL;

    if (pfunc == NULL)
    {
       printf ("fetch module\n");
       pfunc = (funcptr) fetch ("NWPDDRDE");

       if (pfunc == NULL)
       {
          printf("ERROR: fetch failed\n");
       }
    }

    rc = (*pfunc) (pein -> ibuffer,
                   &(pein -> ilaenge),
                   pein -> obuffer,
                   &(pein -> olaenge),
                   pein -> key,
                   &(pein -> klaenge));



Kind regards

Bernd
