YDNRC. In general, the frame steal code has no knowledge that a frame contains a program, or that the program is REFR. The only exception to that is the PLPA and EPLPA virtual storage ranges, for which the frame steal code does steal without paging out, effectively treating everything in those ranges as conceptually REFR for stealing purposes, regardless of the load module attributes.
