The indicator format is a special type of character data. Indicators are all one byte long and can only contain the character values '0' (off) and '1' (on). They are generally used to indicate the result of an operation or to condition (control) the processing of an operation. The default value of indicators is '0'.
You define an indicator field by specifying the
IND keyword in a free-form definition or by specifying N in the
Data-Type entry of
a fixed-form specification. You can also define an indicator field using
the LIKE keyword on the definition specification where the parameter is an
indicator field. Indicator fields are also defined implicitly with the COMMIT
keyword on the file description specification. 
A special set of predefined RPG IV indicators (*INxx) is also available. For a description of these indicators, see RPG IV Indicators.
Indicators are considered to have CCSID(*JOBRUN).
