K2 key in Connections

R Return to the CFS basic task. Entering the command CCn will switch the screen back to the connection number n.

input only applicable to a $CONSOLE connection: specified input is passed to console.

e.g.: tsn.INTR, STA MSG,ALL

n input only possible if multiple $CONSOLE connections have been established in Asynchronous Mode (Command ACn): specified input is passed to the console opened under connection n . e.g.: 1 tsn.INTR, 9 STA MSG,ALL

n Switch to the specified connection.

n is the number of a connection that has already been opened. n can also be the current connection again.

n cmd as above, but together with a command to be executed in the new connection (e.g. 2/STA L). n can also be the current connection again.

The cmd is executed immediately after branching to the subtask. If the connection user is in a mask or Physical Mode Input, cmd is not executed until the next Line Mode Input.

B Pass the K2 key to the communication partner. During extensive screen output, e.g. file entries following an FSTAT command, it can sometimes happen that K2 will only provide a BS2000 command prompt after many screens have scrolled by.

BB The K2 key will be simulated. In contrast to the option B (see above) the remaining extended messages (e.g. FSTAT listings) will be discarded.

^cmd CFS switches back to the basic task, executes the specified command (or sequence of commands), and, if possible, returns to the current connection. A detailed description of ^cmd is to be found in the next section "Escape Symbol in Connections".

The input ^2/ , for example, will open a connection 2 under the same userid, or branch to this connection if it is already open.

? Activating the Help System. The various input possibilities are described.

Notes:

Simply pressing DUE1 key without any parameters is the same as R (Return to CFS).

The special functions of the K2 key in CFS connections described above can be disabled for each connection seperately using the command DKCn (Direct K2-mode for Connection n). For further information, see page 9-.

Administration programs can also be run in connections under $DIALOG that require the K2 key to be pressed to receive an input request. To receive this input request in a CFS connection, press the K2 key, and then when asked, press B (Break).

It can happen in UTM/DCAM applications that K2 + n does not result in a branch to the desired connection n; rather, the switch is back to the basic level of CFS. If this happens, clear the screen with LSP (or Shift + Reset) after pressing K2, and only then enter the connection number n.

It can happen in UTM/DCAM applications such as OASE and ADABAS that the usual CFS Break query does not appear after pressing K2. There are two possibilities to resolve this problem:

- Clear the screen with LSP and then press K2.

- Use the escape symbol ^ / ^n to switch to the basic CFS task, or to another connection.

If the error message "Message cannot be displayed ..." appears in a $DIALOG connection, and the connection does not resume thereafter, pressing K2 and answering B (Break) will repeat the request. This may, under certain circumstances, have to be repeated many times, until the slash ("/"), or the SDF prompt ("KDO:" / "CMD:") appears.

The K2 key can be pressed at any time, for example during DO procedures, or while a program is running. On the other hand, the escape symbol (see next section), can only be entered when input is requested CFS.
