4.2.3.2.3 Changing the Session Function Streams

The following figure summarizes the session functions and their attributes. You cannot specify an input stream for the message (MSG) function. Therefore, this area has been left blank in the figure below.

Intensity (INT) refers to the brightness at which the information is displayed in a stream.

0

The information in the stream is not displayed. You can see the line that the information occupies, but the information itself is invisible.

1

The information in the stream is displayed at normal intensity.

2

The information in the stream is highlighted.

ALARM indicates whether the terminal's audible alarm sounds when information enters the stream.

You can change the input or output streams for any of the session functions, any attributes relating to those streams, and whether the alarm is to sound. For example, you might want your messages to go to the MESSAGE stream instead of the TSOOUT stream or you might not want the TSOIN stream copied to the TSOOUT stream. With the CHANGE.FUNCTION command, you can specify:

The output stream for a session function and the intensity at which the information is to be displayed
The input stream for a session function
Whether information from an input stream is to be copied to an output stream and the intensity at which the information is to be displayed.
Whether the audible alarm is to sound when information enters an input or output stream.

The commands that define the streams and their characteristics for each of the session functions in the default environment are:

     CHANGE.FUNCTION TSO INPUT(TSOIN) COPY(TSOOUT 2) 
        OUTPUT(TSOOUT 1) ALARM(NO) 
     CHANGE.FUNCTION MSG OUTPUT(TSOOUT 2) ALARM(OUTPUT) 
     CHANGE.FUNCTION SM INPUT(SMIN) COPY(SMOUT 0) 
      OUTPUT(SMOUT 2) ALARM(OUTPUT)

For more information, see the syntax description of the CHANGE.FUNCTION command in OS/390 TSO/E Command Reference.
