The OCS Recall Buffer The OCS recall buffer contains the current messages in your OCS message display area
and the past 100 messages that have been displayed. Using the recall buffer, you can
redisplay messages that have been overwritten.
The recall buffer holds only messages that have been displayed, not the ones that are
queued. For example, when there are queued messages and you issue the CLEAR
ALL command, the displayed and queued messages are cleared but only the displayed
messages are placed in the recall buffer.
As the recall buffer fills up, the oldest roll-delete messages are deleted. As time
progresses, the non-roll-delete messages tend to accumulate at the top of the buffer. A
non-roll-delete message in the recall buffer becomes a candidate for deletion only if
you have deleted the message from your OCS window. To accommodate the
non-roll-delete messages, the recall buffer may hold more than 100 messages if there
are no roll-delete messages to delete.
Entering and Exiting the
Recall Buffer
To access the recall buffer from a Tandem 6530 or compatible terminal, press one of
the following from OCS:
PAGEUP, which brings up the previous page of messages in the buffer.
SHIFT and PAGEUP, which brings up the page of the oldest messages, that is, the
top of the buffer.
SHIFT and PAGEDOWN, which brings up the page of messages currently on your
OCS window, that is, the end of the buffer.
To exit from the recall buffer, press F13 (RECALLEND). If you are at the end of the list
of messages in the buffer, you can also press PAGEDOWN to exit.
To access the recall buffer from an IBM 3270 or compatible terminal, you must first
define the recall buffer function keys you want to use (see “The Recall Buffer Function
Keys,” later in this section, for more information). After defining the function keys,
press one of the following from OCS:
PREV, which brings up the previous page of messages in the buffer.
SPREV, which brings up the page of the oldest messages, that is, the top of the
buffer.
SNEXT, which brings up the page of messages currently on your OCS window,
that is, the end of the buffer.
To exit from the recall buffer, press the RECALLEND function key. If you are at the
end of the list of messages in the buffer, you can also press the NEXT function key to
exit.
