<h1 class="topictitle1">Can the length of *CCHAR replacement data change?</h1>
|
||
|
|
<div><p>The length of *CCHAR replacement data can change. This is why *CCHAR
|
||
|
|
replacement data is required to be a variable-length field.</p>
|
||
|
|
<p>The length of the field grows when converting from an SBCS CCSID to the
|
||
|
|
UCS-2 Level-1 CCSID. The length of the field shrinks when converting
|
||
|
|
from the UCS-2 Level-1 CCSID to an SBCS CCSID.</p>
|
||
|
|
<p>For example, you define message description TST0011 as 'Printer &1;
|
||
|
|
has error &2;' in message file MYMSGF that has a CCSID of 65535. '&1'
|
||
|
|
is defined as *CCHAR data (*VARY 2) in length. This is the name of the printer.
|
||
|
|
<var class="varname">&2</var>; is defined as a *CHAR data with a length of 1.
|
||
|
|
This is an error code. Enter the following Send Program Message command to
|
||
|
|
send this message to message queue MYMSGQ:</p>
|
||
|
|
<pre>SNDPGMMSG MSGID(TST0011) MSGF(MYLIB/MYMSGF) TOMSGQ(MYLIB/MYMSGQ) +
|
||
|
|
MSGDTA(X'000400500030F1') CCSID(61952)</pre>
|
||
|
|
<p>X'0004' is the length of the variable *CCHAR data. X'00500030' represents
|
||
|
|
the characters P0 in CCSID 61952. If message queue MYMSGQ has a CCSID of 00037,
|
||
|
|
the replacement data is converted to X'0002D7F0F1' before it is sent to the
|
||
|
|
message queue. If message queue MYMSGQ has a CCSID of 65535, the data is not
|
||
|
|
converted when it is sent to the message queue.</p>
|
||
|
|
<p>Your application programs cannot hard-code the position of the return code
|
||
|
|
in this example. When message queue MYMSGQ has a CCSID of 00037, the return
|
||
|
|
code is 5 bytes into the message text. When message queue MYMSGQ has a CCSID
|
||
|
|
of 65535, the return code is 7 bytes into the message text.</p>
