To display information about the Program Status Word (PSW),
select the PSW option (C) on the MVS path
or enter M.C to fast path.
The panel in the following figure shows the PSW and the
general purpose registers (GPRs) for the most significant CICS® TCBs: the quasi-reentrant
(QR), the concurrent (CO), and the resource-owning (RO). The display
shows only one PSW and set of registers.
The data is taken from
the last time the CICS program
request block (PRB) lost control of the CPU. You can use the PSW display
to help debug CICS problems
such as loops or unusual waits.
