query manager query does not update

We use Query manager queries fairly often, but
not so much with files under commitment control.

We have a table that is journaled and a CLLE program
calling a QM query and passing parameters to update
the status of a particular row.

When control returns to the CLLE, a COMMIT is issued.

The job log shows the parms passed to the QM Query
and the COMMIT command, but a subsequent check
of the table shows the status of the row is unchanged ?

Running a similar update from STRSQL does successfully
update the row in the table.

Is it as simple as adding a COMMIT to the existing QM Query ?
