Do you know of a user error that can cause an ABEND S100 when the BSAM DCBE 
does not specify FIX=USER? Is FIX=USER forced for AC(1) users?

And of course page-fixing a buffer cannot be an input requirement for any 
service that supports unauthorized callers because those callers do not have 
access to page-fix functionality (either by subpool choice or by the services 
that do it).
