|

<div><p>Use the parameters in this topic to determine how the exit program will receive journal entries.</p>
|
|
<p>You use two parameters to communicate between your exit program and the system when you are receiving journal entries. The system uses the first parameter for the contents of one or more journal entries
|
|
that it is passing to the exit program. The exit program uses the first parameter to indicate the block length if the exit program requests block mode.</p>
|
|
<p>The system and the exit program use the second parameter to communicate about status changes, such as requesting block mode or ending the RCVJRNE command. The second parameter is a character field that
|
|
is three bytes long. Following are the possible values for the first byte of the second parameter:</p>

<p>When an N is passed to the exit program in the second byte of the second parameter indicated that no additional journal entries are currently available, it does not necessarily mean that when the exit

be available and depending upon what was specified on the DELAY parameter, may or may not be immediately passed to the exit program. If DELAY(N) was specified the system will wait N seconds before passing

the journal entries to the exit program. If DELAY(*NEXTENT) was specified, the journal entries will immediately be passed to the exit program.</p>
