ABSTRACT OF PROBLEM  
___________________  
With  PJ27334  applied, a non-catastrophic 6C2 dump may occur in  
segment CLMN.  
  

COMMENTS ON PROBLEM  
___________________  
In segment CLMN, after label CLMNIOCF_1D, PJ27334 added code  to  
perform  a  CEBIC macro call.   R15 is being used as a base reg-  
ister for an MFST entry at this point.  The CEBIC macro does not  
save the contents of R15 across the call.  After returning  from  
CEBIC,  R15  is corrupted and, therefore, causes erroneous input  
to the FDCTC macro before label CLMNIOCF_1E.   The  FDCTC  macro  
returns with error and this causes the CTL-6C2 dump.  
  

SOLUTION  
________  
Segment  CLMN, after label CLMNIOCF_1D, now saves R15 in the ECB  
work area before the CEBIC macro call.  After the macro call R15  
is restored and processing continues.
