"F2SA" at offset 4 of a savearea is not a typo. It is an indicator of an internal format that was never documented externally.
It happens to mean that the caller's GPRs 14-12 are saved starting at offset 12 in the area whose address is offset 72 from the start of the savearea you are looking at, and the caller's ARs 0-15 are saved starting at offset 80 from the start of the savearea you are looking at. There are many intra-component savearea conventions.
