Answer Posted / sadiq afroze
TCP places data in TIOA and corresponding entry into TCT.
KCP acquires the transaction identifier from TIOA and
verifies if it is present in PCT.
SCP acquires Storage in Task Control Area (TCA), in which
KCP prepares control data for the task.
KCP then loads the application programs mentioned in PCT by
looking for it in PPT.
If resident ? real storage memory location is not present in
the PPT the control is passed to PCP that loads the
application programs from the physical storage location
address given in PPT. The control is then passed to the
application program (LOAD module).
