ABSTRACT OF PROBLEM
___________________
When  a  non-MDBF  system does a ZRIPL from NORM state, a CTL-22
will occur in segment BLOG on cycle to NORM following the IPL.
 

COMMENTS ON PROBLEM
___________________
 
When a non-MDBF system is IPLed due to a ZRIPL  input,  the  ECB
used for cycle up is the same ECB that executed CTKO in restart.
Before  CTKO  enters  BLOG, an indicator is set in EBSW02.  This
indicator is never reset.   On cycle to NORM,  BLOG  is  entered
again  by  CYAB.   Because the EBSW02 indicator was never reset,
BLOG executes an incorrect path and a CTL-22 results.
 
Segment BLOG first checks the EBSW02 indicator and  then  checks
the  function  indicator in EBW088.  Because of this sequence of
checks, all segments entering BLOG should verify that EBSW02  is
set properly.  However, only CTKO sets EBSW02.
 

SOLUTION
________
Segment  CYAB is updated to turn off the indicator in EBSW02 set
by restart.  BLOG is updated to change the sequence of indicator
checks.  EBW088 is checked before EBWS02.   This prevents  other
enters to BLOG, which may accidentally have the EBSW02 indicator
set,  from  executing  the  wrong path.   CTKO is updated to set
EBW088 before entry to BLOG.
