Thus it avoided having to do a GETMAIN for a small chunk of storage. After I applied it, I did my standard Benchmark and it gave me 15- 18% boost in CPU power. Do not remember if it came out from IBM or some Prehsitoric HACKER. Anyway, IBM made it standard equipment in MVS along with many of the MODS and zaps people dreamed up for MVT. With this mod and other modifications I could outrun an IBM 370-158. OK, so it took a bit more space, power, and A/C.
