Reference

You are looking at a DO loop with a limit of MAXDO, but don't know where it is set. If you just had scan, you loose where you are, and you would have to scan several times to see all the occurrences. Instead, enter "R MAXDO" on the command line, and you get a list of all the references to the field on a single display. If need be, you can look at the context of each statement then return to the list.

The reference command also increments the drill-down level, so an F12 from the list returns to your starting point.

Reference keeps track of every statement where a field, file, indicator, or literal is used. It also tracks some generic object types, so you can see a list of all data structures or subroutines in a program, or record formats in a display file.
