Transfer of Control Between the TSO Application and the IOA Online Facility

You can return to the IOA Online facility from the TSO application by simply exiting the TSO application in a normal manner. However, this method can be time consuming and inconvenient if an ISPF application or a similar TSO application is activated.

If the TSO application can issue a TSO command, it is possible to transfer control to the IOA Online facility, and vice versa, without exiting the TSO application.

While working under the TSO application, for example, under ISPF, issue the command:

TSO CTMTTRA {n | =n}

where n is the online screen number.

The requested screen is displayed as it was when you transferred from it.

To return to the TSO application, use the =6 command (PF06/PF18). The application remains in the same state as when you transferred from it.

It is recommended that you simplify transfer between screens by permanently assigning one of your PFKeys under ISPF (or SDSF, and so on) to the command TSO CTMTTRA. Once this key assignment is made, you no longer need to type the full transfer command. Instead, you merely type the IOA option number or code in the COMMAND field and press the assigned PFKey. You are transferred to the desired screen.

Note: You must activate ISPF under the IOA Online facility if you want to use the control transfer feature.
