<h1 class="topictitle1">Completion with exceptions of errors by the server</h1>
|
||
|
|
<div><p>The server assigns several rather specific major return codes such
|
||
|
|
as 02, 03, 0309, and so on to conditions for which a specific
|
||
|
|
response from the application program is appropriate.</p>
|
||
|
|
<p>A major return code of 02 indicates that the requested input operation
|
||
|
|
completed successfully, but the server is ending the job in a controlled. The application program should complete its processing as quickly as possible. The controlled cancel is intended to allow programs time to end in an orderly
|
||
|
|
manner. If your program does not end within the time specified on the <a href="../cl/endjob.htm">ENDJOB</a> command,
|
||
|
|
the server will end the job without further notice.</p>
|
||
|
|
<p>A major return code of 03 indicates that an input operation completed successfully
|
||
|
|
without transferring any data. For some applications, this might be an error
|
||
|
|
condition, or it might be expected when the user presses a function key instead
|
||
|
|
of entering data. It might also indicate that all the data has been processed,
|
||
|
|
and the application program should proceed with its completion processing. In any case, the contents of the input buffer in the program should be ignored.</p>
|
||
|
|
<p>A major and minor code of 0309 indicates that the server received no data <em>and</em> is
|
||
|
|
ending the job in a controlled manner. A major and minor code of 0310 indicates
|
||
|
|
that there is no data because the specified wait time has ended. Other minor
|
||
|
|
return codes accompanying the 02 or 03 major code are the same as for a 00
|
||
|
|
major code, indicating communications status and the operation to be performed
|
||
|
|
next.</p>
|
||
|
|
<p>A major return code of 04 indicates that an output exception occurred. Specifically, your program attempted to send data when data should have been
|
||
|
|
received. This is probably the result of not handling the minor return code
|
||
|
|
properly on the previous successful completion. Your program can recover
|
||
|
|
by just receiving the incoming data and then repeating the write operation.</p>
|
||
|
|
<p>A major return code of 34 indicates that an input exception occurred. The
|
||
|
|
received data was either too long or incompatible with the record format. The minor return code indicates what was wrong with the received data, and
|
||
|
|
whether the data was truncated or rejected. Your program can probably handle
|
||
|
|
the exception and continue. If the data was rejected, you might be able to
|
||
|
|
read it by specifying a different record format.</p>
|
||
|
|
<p>Two other return codes in this group, 0800 and 1100, are both typically
|
||
|
|
the result of application programming errors, but are still recoverable. 0800
|
||
|
|
indicates that an acquire operation failed because the device has already
|
||
|
|
been acquired or the session has already been established. 1100 indicates
|
||
|
|
that the program attempted to read from invited devices with no devices invited. In both cases, the program ignored the request that is not valid, and the
|
||
|
|
program can continue.</p>
|
||
|
|
<p>No message is issued with a 02 major code or most minor codes with the
|
||
|
|
03 major code, but the other exceptions in this group are typically accompanied
|
||
|
|
by a message in the CPF4701-CPF47FF or CPF5001-CPF50FF range.</p>
