Re: Question on Wait macro
The task will only be dispatched if the top RB is active. So unless someone schedules, e.g., an IRB, the task will be inactive until the RB is active. Nit: in MVS the word "suspend" has a technical meaning that doesn't apply here. -- Shmuel (Seymour J.)

Re: Question on Wait macro
Only the top RB of a task is active; no work can be performed for the older RBs until the older TB goes away or an SVC rearranges the chain, which I believe that only one SVC ever did. When the RB goes into a wait state, the task can only be dispatched after a POST or adding an asynchronous RB, e.g., SVRB, to the chain. Nit: the word "suspend" in MVS that does not apply to an RB. -- Shmuel (Seymour J.)

Re: Question on Wait macro
Well, the earlier RBs are already suspended. The unsatisfied WAIT places the task in the non-dispatchable status. It is possible to add an IRB to the task and the task would be dispatchable and the IRB would run.

Re: Question on Wait macro
What is your question? Show your code that is affected by the issue you perceive.
