Positions 7 and 8 can contain AN or OR to define additional indicators (positions 9 through 11) for a calculation.
The entry in positions 7 and 8 of the line immediately preceding an AND/OR line or a group of AND/OR lines determines when the calculation is to be processed. The entry in positions 7 and 8 on the first line of a group applies to all AND/OR lines in the group. A control level indicator (L1 through L9, L0, or LR) is entered for total calculations, an SR or blanks for subroutines, and a blank for detail calculations.
