Unfortunately no. The TCBADDR will be reused by the next task by the same
user. Ergo, ASID+TCBADDR+JOBNAME is not unique for a task. :(

As it happens,
  1. I cannot modify any of the applications currently running.
  2. I cannot maintain a table of all tasks running and update them.


Also, how do I get a list of all active TCBs in the system ?

I tried the following method.

  PSA -> CVT -> ASCB queue  -> ASXB  -> FTCB (First TCB) and LTCB (last)
                  |
                ASCB        -> ASXB  -> FTCB, LTCB

The problem is, though I get all the ASCBs in the system, I always endup
in the same ASXB ( the one in the current address space). Am I missing
something ?

what should I do to get a list of all active TCBs in the system ?

Thanks in advance for all the help.
