V5R2 change to lock materialization instructions

I found this in the V5R2 Memo to Users draft,
http://publib.boulder.ibm.com/pubs/html/as400/v5r2/ic2924/info/rzaq9.pdf

Changes for lock materialization MI instructions
In V5R2, lock materialization MI instructions MATAOL, MATOBJLK, and
MATDRECL can return a transaction control structure system pointer at the same
offset that a process control space system pointer is returned in prior 
releases. If
the returned system pointer is used in a MI instruction that only accepts a 
process
control space system pointer, that instruction will fail if a transaction 
control
structure system pointer is used. A system pointer to a transaction control 
structure
will be returned if materializing lock information on a transaction object. You 
can
determine if the returned lock information is for a transaction object by 
checking
the value of the Lock scope object type field in the returned data.
