What a very peculiar exception.   I understand that it was probably
easier to accept the overriding DD parm than to check for it and 
reject it, but this sounds dangerous.   If I know at the time I'm 
building JCL that I want to change the characteristics of the 
dataset, why would I wait for the BINDER to do it for me?

Murphy's law dictates that if that override gets put in any BINDER
JCL, THAT job is the one that will be cloned by all the neophytes 
needing BINDER JCL; the feature will be effectively disabled.
