PK73858: ABENDS0C4 IN DSQCISDT IF QMF APF AUTHORIZED OR IN LINKLIST

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If QMF is loaded from LINKLIST, or the QMF loadlib is
  APF authorized, an ABENDS0C4 can occur when the spill file
  (DSQSPILL) is used.  ABEND0C4.

  Code added to DSQCSIDT by PK66525 to detect whether the
  DSQSPILL spill file was allocated to more than one volume
  invoked the standard form of the RDJFCB macro, which worked
  fine unless DSQCSIDT was loaded in protected storage.  If the
  QMF loadlib is APF authorized or added to linklist, DSQCSIDT is
  executed in protected storage.  The standard form of RDJFCB
  should not be used in re-entrant modules.
  

Problem conclusion

• The RDJFCB macro was rewritten in LIST and EXECUTE form,
  which allows it to work in re-entrant code.
  
  When the spill file is opened, DSQCSIDT
  examines the JFCBNVOL value to determine the number
  of volumes allocated to DSQSPILL. If DSQSPILL is allocated
  using the VOL parameter, JFCBNVOL will contain the number of
  volumes allocated.  However, if DSQSPILL is allocated with
  multiple volumes using the UNIT parameter, such as
  UNIT=(SYSDA,5), at the time the spill file is opened, JFCBNVOL
  contains a value of only 1, irrespective of how many volumes
  can be allocated later.  Thus, DSQCSIDT cannot detect multiple
  volumes if the UNIT parm is used.
