TYPCID csid;
TYPOID idint;
const char *idext= "<Obey$Dir>.Datafile";
const mfpos_t zdebut = 1, zfin = 4;
_kernel_oserror *e;
/* gsid must be given a value before calling sp_selectupd */
e= sp_selectupd(gsid, idext, &idint, zdebut, zfin, &csid);

   the app. can now use the idint parameter instead of
   the idext parameter.
   Eg. e= sp_selectupd(gsid, NULL, &idint, ...); */
