Peter Farley noted: > One intriguing use of split format that I thought of would be an RMODE=24 data CSECT for DCB's and other CB's that must live below the line and RMODE=31 for the rest of your code. Avoids dynamic LOC=BELOW storage requests and moves from 31-bit constant areas to 24-bit data areas without sacrificing instruction CSECT reentrancy.
That's just one of many uses of RMODE=SPLIT. You can largely eliminate the need for a module of one RMODE to load a module of another RMODE; plus, the binder will resolved external references "across the line", so each module can refer to multiple points in the other.
