To answer directly, "no". The system will always allocate storage of the type requested from the area used for that type. But of course there is no such thing as "from LSQA". LSQA is just a group of subpools that are part of the set of authorized-only private area subpools. As other posts mentioned, whether below 16M or above 16M, "user subpools" start with the "low addresses" and work their way up and "system private subpools" (of which LSQA is just one) start with the "high addresses" and work their way down. The "region size" is an upper bound to the "work their way up" portion. The "work their way down" portion, however, takes precedence, and can and will expand into the user region. Once that happens, the effective user region is reduced. This "low water mark" of the system region becomes the "high bound" of the user region. While REGION=0M, in the absence of other things, does indicate not to reserve any particular amount for system subpools, many customers use their IEFUSI exit to provide a limit to what REGION=0M can provide.
