Guess I am now.  Never did this particular thing.

Most/all of my usage of CREPRC has been for creating detached processes.  Now 
that you made me think (I hate when that happens) I seem to recall that for 
detached processes the PQL parameters are used for defaults when a particular 
parameter is not in the item list.  I also seem to recall that that may not 
happen for other than detached processes.  Didn't do much of that.

Regardless, if using a PQL parameter, unless they have been customized, (which I 
did on systems running our software), the value may not be of much use, if it is 
too low, and I also seem to recall that the supplied values were usually too 
low.  Thus my initial puzzlement as to why you wanted to use any PQL parameters.

My solution was to have some application data, one set for each detached 
processes application, which specified needed parameters and such.  Thru time, 
more and more of our applications used detached processes, and the design turned 
out to be quite helpful.  Not so many people working with "terminals" these 
days, and more services serving trading partner inquiries, orders, and such.
