Receive <strong>Data</strong> <strong>Queue</strong> (QRCVDTAQ) API<br />
A field of at least the length of the value specified for the MAXLEN parameter on the Create <strong>Data</strong><br />
<strong>Queue</strong> (CRTDTAQ) command. This field contains the data received from the data queue.<br />
Note: If the length of this field is larger than the size of the message received, only the number of<br />
characters (beginning from the left) as defined by the message received from the data queue are<br />
changed. If the length of this field is smaller than the value specified for the MAXLEN parameter<br />
on the Create <strong>Data</strong> <strong>Queue</strong> (CRTDTAQ) command, and the actual length of this field is not specified<br />
in the size of data receiver parameter, unexpected results can occur.<br />
If the length of this field is specified in the size of data receiver parameter, the data received will be<br />
truncated if it is longer than the size specified.<br />
Wait time<br />
INPUT; PACKED(5,0)<br />
The amount of time to wait if no entries exist on the data queue.<br />
When no entries are on the data queue, the wait time parameter (in seconds) specifies the following:<br />
< 0<br />
Waits forever.<br />
0<br />
Continue processing immediately. If no entry exists, the call completes immediately with the<br />
length of data parameter set to zero.<br />
> 0<br />
The number of seconds to wait. The maximum is 99999 which allows a wait time of<br />
approximately 28 hours.<br />
Note: If the wait time value is less than or equal to 2, the job does not leave the activity level (for 2<br />
seconds). This is described as a short wait. For more details on activity levels and implementation<br />
applications, see the Work Management book.<br />
Optional Parameter Group 1<br />
Key order<br />
INPUT; CHAR(2)<br />
The comparison criteria between the keys of messages on the data queue and the key data<br />
parameter. When the system searches for the requested key, the entries are searched in ascending<br />
order from the lowest value key to the highest value key until a match is found. If there are entries<br />
with duplicate keys, the entry that was put on the queue first is received. Valid values are:<br />
GT<br />
Greater than<br />
LT<br />
Less than<br />
NE<br />
Not equal<br />
