ABSTRACT OF PROBLEM
___________________
With PJ27393 applied, ACPL cannot complete.


COMMENTS ON PROBLEM
___________________
ACPL  makes  use of the IDSFCZ DSECT, but does not use the FACZC
macro to calculate file addresses.  Instead, it calls  FACS  and
then  copies  values  returned  by  FACS  into a FACZC parameter
block.  As a result of changes to IDSFCZ made by  DECB  support,
PJ27393, the code in the CALLFACS routine in ACPL now places the
file address returned by FACS in the wrong location.  Any subse-
quent  attempt  to  use the returned file address by referencing
IFCZADR fails because the fullword at that location  contains  a
value of zero.


SOLUTION
________
Changed CALLFACS routine in ACPL to use FACZC instead of calling
FACS.
