<snip> assuming we are careful to return R15=0 in our exit routines and not change anything in the passed parameters, could that still affect or override in any way the results of the default or system exit routines already in effect for those exit points? </snip>
No, it could not. <snip> (Now why certain IBM components continue not to use it is another matter.) </snip> Because, presumably, there has been not enough call to do so (and there is, of course, a cost for implementation). If you have a reason for wanting/needing a particular exit to exploit the dynamic exits facility, then please submit an RFE. When the facility was developed, we took a stab at which existing exits that we thought were most likely to be of help to the most customers. And I'd hope that new exits use it. <snip> SYS.IEFUSI AND SYS.IEFACTRT </snip> I agree with Tony H's point that you need to consider whether you might also need the other cases such as SYSSTC.
