The LR Indicator, if specified in positions 7 and 8, causes the calculation to be done during the last total calculation time. Note that the LR indicator cannot be specified in subprocedures.
If there is a primary file but no secondary files in the program, the LR indicator is set on after the last input record has been read, the calculations specified for the record have been done, and the detail output for the last record read has been completed.
If there is more than one input file (primary and secondary), the programmer determines which files are to be checked for end-of-file by entering an E in position 19 of the file description specifications. LR is set on when all files with an end-of-file specification have been completely read, when detail output for the last record in these files has been completed, and after all matching secondary records have been processed.
When the LR indicator is set on after the last input record has been read, all control indicators L1 through L9 defined to the program are also set on.
