Hi Bharath,
Re-entrancy property means the capability of a program to behave differently for different invocations under different conditions. Too theoritical !!! In easy terms and with CICS program examples - each CICS program is invoked by a unique transaction and the program again can start another program by issuing transaction -
EXEC CICS START TRANS('T123') END-EXEC.
Like this way a program can re-start itself also. Now, with this again-and-again re-entering you can insert different processing logics for different entry , like -
If the program is invoked for first time
Do Logic 1
If the program is invoked for first time
Do Logic 2
If the program is invoked for first time
Do Logic 3 ....
This property is Re-entrancy . In CICS terminology, this re-entrancy property is called Quasi-Reentrancy.
