Hi. I would like to submit an RFE to IBM to support a LOC=32 parameter to GETMAIN, giving 32-bit programs access to a full 4 GiB instead of the current 2 GiB provided by LOC=31.
Impossible. That area is not mapped by an STE in any current IBM Z hardware. You need a RTE (3rd) to get to it. That makes it "above the bar" storage.
Do what everyone else does. Use IARV64 REQUEST=GETSTOR with either USE2GTO32G=YES or USE2GTO64G=YES to acquire space in that area.
