Re: Record size limitation in RPG - MQ Series

["Colin Williams" <colin.williams@xxxxxxxxxxxx>]

Carl

user spaces are actually pretty easy to use.

Use the API QUSPTRUS, Retrieve User Space Pointer, in your RPG, to point a
32K variable in your RPG to a user space.  Then when you update the
variable, you will be writing to the user space.

When you fill up the variable, add 32k to the pointer, clear the variable
and do it again until you've processed the whole message.

Pass the message length and the pointer to the user space to MQPUT, and your
away. Did the same thing 8 years ago, and im sure that was on V3R7

cheers
