The "doc" actually does say so. But it's not surprising you didn't notice it, because it's in the "guide" (and not in a section specifically for IARV64) rather than in the "reference" for IARV64. The macro has "The initial value of storage within a memory object is binary zero." The assembler services guide has "IARV64 GETSTOR service creates memory objects; storage is cleared to zeros". We will look into updating the reference's GETSTOR function to have the same information. Peter Relson z/OS Core Technology Design
