Indicators that you have defined as overflow indicators, control level indicators, record identifying indicators, field indicators, resulting indicators, *IN, *IN(xx), *INxx, or those that are defined by the RPG IV language can be used to condition files, calculation operations, or output operations. An indicator must be defined before it can be used as a conditioning indicator. The status (on or off) of an indicator is not affected when it is used as a conditioning indicator. The status can be changed only by defining the indicator to represent a certain condition.
