A CTL-3 system error may occur during DBCLS REUSE processing when using  
a commit scope and TPFDF Transaction Manager services, introduced by TPF  
APAR PJ26746.  A TPFDF APAR (PQ51339) and a TPF APAR are required for  
associated changes.

COMMENTS:
A CTL-3 system error may occur during DBCLS REUSE processing from TPF  
segment CL80 because CL80 uses the DBIFB external macro.  An external macro
is not allowed from within internal TPFDF processing.


SOLUTION:
TPF segment CL80 has been updated to use new TPFDF restricted macro DFIFB
instead.
