True. But it might well increase the storage allocation. Consider an application that does a variable-length GETMAIN so that it can, in effect, allocate the entire region (and possibly sub-manage the storage then). I believe HLASM might do just that. The question is then what does the application do with that allocated storage. If the extra storage isn't used, then it won't matter much (if at all) that it has been allocated. But if it is used, then anything could be going on, whether it's unnecessary clearing or anything else. Without knowing the details of the application, no one can do more than guess.
