IARV64 makes above-the-bar storage available in chunks, one mibibyte at a time; and requesters must submanage this storage themselves. IARCP64 makes above-the-bar storage available in chunks, one mibibyte at a time, and submanages this storage as pool of cells of the size requested on IAR64CP REQUEST=BUILD. Storage within any such one mibibyte chuck is used only by callers of IARCP64 using the same INPUT_CPID. IARST64 makes above-the-bar storage available in chunks, one mibibyte at a time, and submanages this storage as pool of cells of the requested size. Storage within such a one mibibyte chunk can be used by any caller of IARST64 whose requested size and storage attributes match the cell size and storage attributes being used for that one mibibyte chunk. > Does the 'CP' in 'IARCP64' stand fror 'Cell Pool'?
