Fullscreen TPUTs will continue to be displayed in the 3270 emulator session. Required input to satisfy a fullscreen TGET must be entered in the 3270 emulator session. For example, if the user from ISPF GUI mode invokes SDSF through its fullscreen TPUT interface (that is, the user enters TSO SDSF from an ISPF command line) the SDSF screens are displayed in the 3270 emulator screen.

However, if the user invokes SDSF through the ISPF interface ISPEXEC SELECT PANEL(ZSDSFOP2) NEWAPPL(ISF) then the SDSF screens are displayed in the ISPF GUI mode window just like any other ISPF panel.

Users running fullscreen applications like RMFMON, CSP, and OMVS from an ISPF GUI session with GUI TSO line mode support should first suspend the ISPF/TSO Window. This forces all fullscreen and line mode data to appear in the 3270 screen until the completion of the fullscreen application. The ISPF/TSO Window should be resumed at the completion of the fullscreen application processing.

You can query the current status of the ISPF/TSO Window using the CONTROL TSOGUI QUERY service. You can suspend and resume the window using one of these methods:

1. ISPF CONTROL Service

   CONTROL TSOGUI  QUERY|OFF|ON

   QUERY

   Calls for the current status of the ISPF/TSO window. One of these return codes is shown:

   0

   Either the user is not running ISPF GUI with TSO line mode support, or TSOGUI is off. All TSO input and output is directed to the 3270 session.

   1

   All TSO line mode output is displayed in the ISPF/TSO window. Line mode input must be entered into the ISPF/TSO window's input field.

   OFF

   Specifies that the ISPF/TSO window is suspended. All fullscreen and line mode data appears in the 3270 window until CONTROL TSOGUI ON is issued.

   ON

   Specifies that the ISPF/TSO window is resumed. All TSO line mode output and input is directed to the ISPF/TSO window.

   Note:

   1. If you do not run ISPF GUI with TSO line mode support, issuing CONTROL TSOGUI results in no operation being performed (NOP).
   2. CONTROL TSOGUI defaults to ON during ISPF GUI session initialization.
   Example CLIST:

   PROC 0
   ISPEXEC CONTROL TSOGUI QUERY
   SET &TSOGUIST= &LASTCC
   IF (&TSOGUIST = 1) THEN +
     DO
      ISPEXEC CONTROL TSOGUI OFF
     END
   ISPEXEC SELECT CMD (OMVS)
   IF (&TSOGUIST = 1) THEN +
     DO
      ISPEXEC CONTROL TSOGUI ON
     END

2. ISPF TSOGUI command
   The TSOGUI command is found in the ISPF command table as:

   SELECT PGM(ISPISM) PARM(TSOGUI,&ZPARM)

   You can enter TSOGUI OFF or TSOGUI ON from any ISPF command line.
