CALL ZVERIF (IXDIV,IFRETN,CHIDENT)
This routine will go to ZFATAL when it finds corruption of
the selected areas of the Zebra stores, if the users has
so requested with IFRETN, or if automatic verification
is running.
ZVERIF will print details about all inconsistencies which it finds.
Two separate routines, ZVDO1 and ZVDO2, first check that the global Zebra parameters in /MZCA/ and the store table for each store corresponding to /MZCC/ are intact. If this is not the case there is serious trouble, and therefore these two routines go to ZFATAL unconditionally.
