Yes, after a fruitless search through the text units I found the flag in the RB. I will implement a configuration option so customers can turn off the allocation messages when doing initial check-outs or other operations involving large numbers of members.
Thanks for the tip!

In a batch program (HSIPINQ) which allocates lots of DDs, I use the flag in both the allocation and deallocation requests to reduce spooled output size, as well as the number of pages one has to scroll down to get to the start of the SYSPRINT report. (Sometimes this is being viewed outside SDSF where N 3 works well.) The main purpose I like all those allocation and data set disposition messages in the general case is so that I can quickly see which data sets are allocated at the time of an abend, and can usually figure out which DDs are allocated to which data sets. Naturally, the data sets disposed of after the abend are the ones which were allocated at the time of the abend. Of course, sometimes customer flower boxes from their IEFACTRT routine can be helpful in this area too. Anyway, in the SYSPRINT report line which reports the data sets as they are processed I now also display the DD name just in case it's needed. IIRC, I went looking for this flag one day when trying to figure out how BPXWDYN can do allocations and deallocations without generating such messages. Given its component prefix, perhaps it was written with a view to operating in spawned address spaces which usually leave no spooled relic of their existence.
