• ATTN KEY FUNCTION CHANGE IN NETVIEW ACCESS SERVICES R2
  
  THIS INFO APAR DESCRIBES THE CURRENT IMPLEMENTATION OF THE ATTN
  KEY FUNCTION IN NETVIEW ACCESS SERVICES RELEASE 2, (566536501
  R200 OR R201) AS IT HAS CHANGED WITH APAR PL58288.  READERS OF
  THIS INFO APAR SHOULD BE FAMILIAR WITH THE NETVIEW ACCESS
  SERVICES FUNCTIONS.
  
    ATTN KEY - GENERAL USE
  
  ATTENTION (ATTN) KEY PROVIDES A MEANS OF GETTING A HOST
  PROGRAM'S ATTENTION.  THE HOST PROGRAM THAT THE TERMINAL IS IN
  SESSION WITH DETERMINES HOW THE ATTN KEY IS USED.  THE MAJORITY
  OF THE IBM APPLICATIONS (SUCH AS TSO) IMPLEMENT THE ATTN KEY AS
  AN INTERRUPT KEY ALLOWING USERS TO TERMINATE THE CURRENT TASK.
  THE ATTN KEY IS COMMONLY USED TO STOP A LENGTHY TRANSACTION.
  ATTN KEY IMPLEMENTATION IN NETVIEW ACCESS SERVICES WITH PL58288
  THE USE OF THE ATTN KEY UNDER NETVIEW ACCESS SERVICE (NV/AS) IS
  IMPLEMENTED DIFFERENTLY FROM OTHER IBM APPLICATIONS.  THE
  CURRENT ATTN KEY IMPLEMENTATION IN NETVIEW ACCESS SERVICES
  RELEASE 2 WITH APAR PL58288 IS AS FOLLOWS:
  1.  ATTN KEY DOES NOT PERFORM ANY FUNCTION WHEN USED AT THE
      NV/AS APPLICATION SELECTION MENU OR ANY OF THE NV/AS
      ADMINISTRATION SCREENS.
  2.  IN RELAY MODE
         IF THE ATTN KEY IS DESIGNATED AS THE ESCAPE KEY, YOU MAY
         USE IT TO RETURN FROM AN APPLICATION SESSION TO THE
         NV/AS APPLICATION SELECTION MENU.
         IF THE ATTN KEY IS DESIGNATED AS THE JUMP KEY FOR AN
         APPLICATION YOU MAY USE IT TO SWITCH DIRECTLY TO THAT
         APPLICATION FROM OTHER SESSIONS.  FOR INSTANCE, IF THE
         ATTN KEY IS DEFINED AS THE JUMP KEY FOR TSO, WHILE
         WORKING IN A CICS SESSION, YOU MAY SWITCH DIRECTLY TO
         THE TSO SESSION USING THE ATTN KEY.
         IF THE ATTN KEY IS NOT USED AS THE ESCAPE KEY OR AS A
         JUMP KEY, THE ATTN KEY CAN BE USED ALONG WITH OTHER
         KEYSTROKES TO INTERRUPT THE CURRENT TRANSACTION RUNNING
         ON AN APPLICATION.
  
  THE FOLLOWING SCENARIO PROVIDES A DETAILED DESCRIPTION OF HOW
  ATTN KEY IS SUPPORTED:
  SCENARIO:
    *---------*          *---------*               *----------*
    | TERMINAL|          |         |  SESSION 1    |          |
    |         |----------|         |---------------| APPL  1  |
    |         |          |         |  (FOREGROUND) |          |
    *---------*          | NV/AS   |               *----------*
                         |         |               *----------*
                         |         |  SESSION 2    |          |
                         |         |---------------| APPL  2  |
                         |         |  (BACKGROUND) |          |
                         *---------*               *----------*
  A USER LOGS ONTO NV/AS AND ESTABLISHES TWO RELAY MODE SESSIONS
  (SESSION 1 AND SESSION 2). WHILE WORKING ON SESSION 1, THE USER
  STARTS A TRANSACTION THAT REQUIRES A LONG PROCESSING TIME. AS
  THE TRANSACTION IS BEING EXECUTED THE USER'S KEYBOARD IS LOCKED
  AND AN X-CLOCK STATUS SYMBOL IS DISPLAYED ON THE TERMINAL.  AT
  THIS POINT THE USER MAY WISH TO:
  1.  SWITCH TO ANOTHER SESSION (I.E. SESSION 2) TO PERFORM OTHER
      WORK WHILE THE TRANSACTION ON SESSION 1 IS BEING PROCESSED.
      OR
  2.  INTERRUPT AND TERMINATE THE TRANSACTION ON SESSION 1 (IF
      THE TRANSACTION IS MISTAKENLY ENTERED OR IN A LOOP).
  THE FOLLOWING CHART SHOWS THE VARIATION OF KEYSTROKES NEEDED TO
  ACCOMPLISH THESE TWO ACTIONS DEPENDING ON WHETHER OR NOT THE
  ATTN KEY IS USED AS THE ESCAPE KEY OR A JUMP KEY.  (*** NOTE 1)

  NOTE 1 - TERMINOLOGY
   JUMP KEY - WHEN MULTIPLE RELAY SESSIONS ARE ESTABLISHED, A
   JUMP KEY IS USED TO SWITCH FROM ONE APPLICATION DIRECTLY TO
   ANOTHER.   A USER MAY ASSIGN A PF, PA, OR ATTN KEY AS A JUMP
   KEY
   ESCAPE KEY - THE ESCAPE KEY IS USED TO RETURN FROM AN
   APPLICATION SESSION TO THE NV/AS APPLICATION SELECTION MENU.
   A USER MAY ASSIGN A PF, PA OR ATTN KEY AS THE ESCAPE KEY.
   COMMAND KEY & COMMAND PREFIX - THE COMBINATION OF THE COMMAND
   KEY AND THE COMMAND PREFIX ENABLES A USER TO SEND A PF, PA
   OR ATTN KEY STROKE TO AN APPLICATION.  FOR INSTANCE, IF YOU
   DON'T HAVE PF24 KEY ON YOUR KEYBOARD AND "$$" IS DEFINED AS
   THE COMMAND PREFIX, YOU MAY TYPE IN "$$PF24" AND PRESS THE
   COMMAND KEY TO SEND THE PF24 KEYSTROKE TO AN APPLICATION.
  
  NOTE 2 - WHEN THE USER RETURNS TO SESSION 1, IF THE TRANSACTION
   IS COMPLETED, THE OUTPUT OF THE TRANSACTION IS DISPLAYED.  IF
   THE TRANSACTION IS NOT COMPLETED, THE OLD SESSION 1 SCREEN IS
   DISPLAYED WITH THE X-SYSTEM SYMBOL.
  
  NOTE 3 - "$$" IN "$$ATTN" IS A SAMPLE COMMAND PREFIX.  IF A
   DIFFERENT CHARACTER STRING IS DEFINED AS THE COMMAND PREFIX,
   SUBSTITUTE "$$" WITH THE DEFINED COMMAND PREFIX.
