You can specify control level indicators (L1 through L9 and LR) in positions 7 and 8 of the calculation specifications.
If positions 7 and 8 are blank, the calculation is processed at detail time, is a statement within a subroutine, or is a declarative statement. If indicators L1 through L9 are specified, the calculation is processed at total time only when the specified indicator is on. If the LR indicator is specified, the calculation is processed during the last total time.
