That observation applies to EVERY control block EVERYWHERE
You have a misunderstanding about how running units of work are
represented in MVS.
IHASRB is to SRBs somewhat like IEZATTCH is to TCBs -- a parm list used
only to "describe and start" the unit of work. It is *not* like IKJTCB
-- a control block used to maintain the execution/dispatch status of a TCB.
When a preemptible SRB is suspended, an SSRB (mapped by IHASSRB) is
acquired and formatted. When the SRB starts running again, the SSRB is
freed ... and so forth.
