Mark,

EXIT53 did not exit in z/OS 1.4 nor in 1988, so I don't see how you
could have been running it since then.   

You didn't answer a question I asked from earlier.   Is this failing in a test
environment, or did you upgrade the production environment with no 
other changes from 1.7 other than a reassembly / relink of this EXIT53? 
Or did it only exist as EXIT03 in 1.7?   

If using it as EXIT53 is new, don't forget that exits running in the
user environment must be loaded into common storage.  Assuming
you have both an EXIT03 and EXIT53 with similar code, you load it
as follows:

LOADMOD(MYEXIT03) STORAGE=PVT             
LOADMOD(MYEXIT53) STORAGE=CSA     

Since you can load new exits dynamically, maybe you should
assemble / link the sample "as is" and see if it works in your
environment.    I'm pretty sure this is a "user error" of some
sort.
