You could always try simply writing the control record with SFLDSP off and SFLDSPCTL on. The subfile just wouldn't appear on the screen so no one could change any records.

Sorry, not sure I understand. I've not seen the keyword DSPCTL before?
And surely if I set SFLDSPCTL to *OFF I won't be able to update any figures on
the control record?

Yes, PROTECT would be one way but would require setting the indicator
on the PROTECT to default to NOT(PROTECT) and updating all the subfile
records.
But you can use the DSPCTL and SFLDSPCTL keywords. To change just the
control record, set the indicators and redisplay the same SFLCTL
record but SETOF the indicator(s) for SFLDSPCTL.
