Hi everyone,

I have a MQGET coded which completed with a Return and reason code of 0, but the DATA-LENGTH field is zero and there doesn't seem to be any data returned.

Code:
MQ-GET-BUF-LEN   =0000003301       
MQ-DATA-LENGTH   =0000000000       
MQ-COMPL-CODE    =0000000000       
MQ-REASON-CODE   =0000000000       


my GET options are set as such.
Code:

 COMPUTE MQGMO-OPTIONS  = MQGMO-NO-SYNCPOINT +     
                          MQGMO-WAIT      +         
                          MQGMO-ACCEPT-TRUNCATED-MSG


Does anyone have any bright ideas?

I think the problem is with the message - not my GET.

could it be a consequence of the option
Quote:
MQGMO-ACCEPT-TRUNCATED-MSG
?

might be worth reading the manuals to see what happens to a MQPUTs with zero length message
if it can be done then You will have to do some more checks in Your application

Did you specify MQ-DATA-LENGTH during MQGET call?

I think the MQ-DATA-LENGTH is output. I do set the MQ-GET-BUF-LEN.

I have seen that the message on the Q is missing the data portion - though why is still a mystery.
