No. It means that the code will run correctly even if the OS refreshes it from DASD. That might mean that it is R/O, or it might only mean that the changes are not relevant to correct operation, e.g., storing data for dump analysis that the module never looks at again.
Now, IMHO it's bad form to play such games, but it's legal. -- Shmuel (Seymour J.)

It makes complete sense that REFR does. IIRC, back in the very old days, there was the "SVC transient" area (2K or 4K) into which an type 3 SVC or one of the parts of a type 4 SVC was dynamically loaded. These modules were "refreshable" which I think meant "MVS, you are allowed to refetch this module from disk and just continue running it because I guarantee that the code & data areas in it are not ever going to change". > > sas > > -- Once a government places vague notions of public safety and security above the preservation of freedom, a general loss of liberty is sure to follow.
