Problem summary

  * USERS AFFECTED: HATS 5250 clients using SysReq mode.         *
  ****************************************************************
  * PROBLEM DESCRIPTION: Users of the SysReq mode in 5250        *
  *                      sessions encounter a problem when an    *
  *                      error(an Operator-Input Error XII) is   *
  *                      thrown by the host. While still in      *
  *                      sysReq mode, the user tries to key      *
  *                      in data on fields which are not         *
  *                      "input-fields" under the SysReq mode,   *
  *                      since the SysReq mode will have only    *
  *                      the "SysReq line"(at the bottom the     *
  *                      session screen) as the input field      *
  *                      which ideally needs to be used. This    *
  *                      results in the "Cursor on the           *
  *                      protected area of the display" error    *
  *                      message. At this point, the user        *
  *                      presses an Enter key (HATS sends the    *
  *                      AID key only to the host) and this      *
  *                      results in keying in invalid/wrong      *
  *                      data on the input fields of the host    *
  *                      application.                            *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  While the user is in sysReq mode and tries to enter invalid
  data in an input field, the user is thrown an error saying
  "Value entered for field is not valid". The user would use the
  SysReq mode to enter the correct data. When this sysReq mode
  is being processed, the user might not use the SysReq line to
  send the data, rather enter into an Error condition by trying
  to key in data on the original input field(which would be
  protected in the SysReq mode). So, as the "Cursor in protected
  area of the display" message is shown, HATS enters an ERROR
  mode. The main problem addressed by this APAR is the handling
  of the ERROR mode within the SysReq mode.
  

Problem conclusion

• There are only two valid combinations in SysReq mode, one
  being an AID key followed by the SysReq key(or SysReq mode)
  and the other being the ERROR condition while in the SysReq
  mode. This fix involves clearing the SysReq mode at the right
  juncture so as to handle the ERROR mode(while still being in
  the SysReq mode). When these modes are cleared, the FFT(Field
  Format Table) would be restored back to the original screen
  and this would enable HATS to send the data along with the AID
  key to the host and hence not allow the invalid data to be
  accepted by the host application.
