SYNADRLS completion codes

When the system returns control to the problem program, the low-order byte of register 0 contains a completion code. The 3 high-order bytes of register 0 are set to 0.

The SYNADRLS completion codes are:

Completion Code (0)	Meaning
00 (X'00')	Successful completion.
08 (X'08')	Unsuccessful completion. The buffer and save areas were not released; the contents of register 13 remain unchanged. Register 13 does not point to the save area provided by the SYNADAF macro, or this save area is not properly chained to the previous save area.
