Receive Data Queue (QRCVDTAQ) API
EQ
GE
LE
Equal
Greater than or equal
Less than or equal
This parameter is ignored if the length of key data is zero. A value of blanks is recommended if the
length of key data is zero.
For example, assume a keyed data queue contains these three entries:
Physical Entry 3-Character Key
1 GGG
2 XXX
3 AAA
If a key order of LE is specified with key data of XXX, entry 3 would be received. If the same
values were specified on a subsequent request, entry 1 would be received.
Length of key data
INPUT; PACKED(3,0)
The length of the key data parameter. If this parameter is specified, it must be zero for nonkeyed
data queues. For keyed data queues it must be equal to the length specified on the KEYLEN
parameter on the Create Data Queue (CRTDTAQ) command.
Key data
I/O; CHAR(*)
The data to be used for receiving a message from the data queue. The key of the received message is
also returned in this field. It may be different than the key specified to search for. For example, if
the key data parameter is set to AA on input with the key order parameter set to GE (greater than or
equal to), the key of the record that is actually received could be AB or anything else greater than or
equal to AA. The key data parameter is set to the actual key of the received data when the API
returns.
Length of sender information
INPUT; PACKED(3,0)
The length of the sender identification parameter. Valid values are:
0
No sender information is returned.
8
Returns only the bytes returned and bytes available fields of the sender information.
> 8
Return as much sender information as the length allows.
