OW24689: USER RUNNING RMFMON, CSP, OR OMVS IN ISPF GUI ENVIRONMENT ENCOUNTER ERRORS INCLUDING HANGS .

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When running ISPF GUI with TSO GUI linemode support ( i.e., TSO
  linemode data output and input in an ISPF/TSO GUI Window ),
  running some full screen applications such as RMFMON , CSP and
  OMVS results in various errors. These errors include screen
  erasure errors and hangs requiring the userid to be canceled.
  ISPF documents that fullscreen TPUTs from an application will
  appear in the emulator screen ( 3270 window ), while
  non-full screen TGETs will go to the ISPF/TSO GUI window.
  The problem applications have a mixture of fullscreen TPUTs
  and linemode TGETs.  This results in the displays going to
  the 3270 window, but the line mode TGETs are done against
  the ISPF/TSO GUI window, resulting in the error or wait .

Local fix

• From the 3270 window try doing a PA1/ATTENTION to breakout
  of the hang/wait and then push the OK button on the ISPF/TSO
  GUI window... RMS - 01/13/97

  ****************************************************************
  Some fullscreen applications like RMFMON, CSP, and OMVS issue
  fullscreen TPUTS but linemode TGETS.  When running these apps
  from an ISPF GUI session with TSO linemode support the displays
  appear back in the 3270 session but the input is requested from
  the ISPF/TSO Window since it is a linemode TGET.
  

Problem conclusion

• User's running fullscreen applications like RMFMON, CSP, and
  OMVS from an ISPF GUI session with GUI TSO linemode support
  should first suspend the ISPF/TSO Window to force all fullscreen
  and linemode 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 this fullscreen
  application.  The user can query the current status of the
  ISPF/TSO Window using the new 'CONTROL TSOGUI QUERY' service,
  and can suspend and resume this window using one of the two
  methods described below:
  
     1. New ISPF Service -
          CONTROL TSOGUI  QUERY|OFF|ON
  
          QUERY - gives current status of ISPF/TSO window
  
             Return Code = 0 - means either the user is not
                               running ISPF GUI with TSO linemode
                               support  or
                               TSOGUI is OFF - all TSO input and
                               output will be directed to the 3270
                               session
  
                           1 - means all TSO linemode output will
                               display in the ISPF/TSO Window and
                               linemode input must be entered into
                               the ISPF/TSO Window's input field.
  
          OFF - specifies that the ISPF/TSO Window is suspended
                and all fullscreen and linemode data will appear
                in the 3270 window until CONTROL TSOGUI ON is
                issued
           ON - specifies that the ISPF/TSO Window is to be
                resumed and all TSO linemode output and input will
                be directed to the ISPF/TSO Window.
  
        Notes:
            1. CONTROL TSOGUI is a NOP if not running ISPF GUI
               with TSO linemode support.
            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.  New ISPF command - TSOGUI
  
         Add the TSOGUI command to your ISPF command table:
            SELECT PGM(ISPISM) PARM(TSOGUI,&ZPARM)
         For results as described above for CONTROL TSOGUI OFF or
         ON, from any ISPF command line enter:
              tsogui off or tsogui on
