Messages are normally released to the queue when a checkpoint is issued, the programs issues the next GN to the message queue or when the program ends. All these will commit any changes to the database. A PURG call can be used to release the message without committing changes to the database. It is also used if you have a modifiable PCB and the destination needs to be changed (that is, you are sending output to more than one destination).
