The Send/Receive Data Queue commands provide front ends to the system
supplied QSNDDTAQ and QRCVDTAQ programs. The commands can be helpful
when a minimal number of entries needs to be sent or received from a
data queue.
If a large volume of entries needs to be sent or received, the system
supplied programs should be used directly.
A typical send command would be:
SNDDTAQ DTAQ(DTQ1) ENTLEN(50) ENTRY('xxxxxxxx')
The RCVDTAQ command returns variables and can only be used in a CL
program. A typical command would be:
RCVDTAQ DTAQ(DTQ1) ENTLEN(&ENTLEN) ENTRY(&ENTRY)
A WAIT parameter is supported on RCVDTAQ. The default is *NOMAX. If
a wait time is specified and a timeout occurs, the ENTLEN return
variable will contain 0.
Send Data Queue command parameters *CMD
-----------------------------------
DTAQ The qualified name of the data queue to send to.
The library defaults to *LIBL.
ENTLEN The field length of the entry to be sent. The value
cannot exceed the value specified on the CRTDTAQ
command. A maximum of 512 is allowed.
ENTRY The data to be sent as the entry.
KEYLEN The key length. The default is *NONE.
KEY The key value. The default is *NONE.
Receive Data Queue command parameters *CMD
-------------------------------------
DTAQ The qualified name of the data queue to receive
from. The library defaults to *LIBL.
ENTLEN The length of the entry returned. This must be
declared as *DEC LEN(5 0). If a 0 is returned, a
WAIT timeout has occurred.
ENTRY The data received. This must be declared as *CHAR
LEN(512). The entry length can be less.
WAIT The wait time in seconds. The default is *NOMAX.
ORDER The order to search a keyed data queue. The default
is EQ. If the data queue is not keyed, the entry is
ignored. Other values that may be specified are NE,
GE, LE, GT, and LT.
KEYLEN The key length. The default is *NONE. If you are
using a keyed data queue, you must specify an entry.
KEY The key to the record you want returned. The
default is *NONE.
