The Input Session Id field specifies the session to be acted on by DBCHCL.
|reads (RSUP; IRQ; FET; REW; ERQ; ABT; DSC)
The application program copies the value from Output Session Id into Input Session Id.
If the application program uses the same DBCAREA to run sessions concurrently, it should save Output Session Id from each session’s logon. The application program must store the appropriate value of Output Session Id in Input Session Id whenever it intends the next DBCHCL call to affect a different session.
Connects only take place by calls to DBCHCL for the Connect function.
