The DEF_HEAD command is used to define one or more heading lines for inclusion on a report.
Only fields of type Alpha, Packed and Signed may be specified. RDMLX field types cannot be specified.
Heading lines are only printed when the condition specified in the TRIGGER_BY parameter is true and are used to begin or trigger a new page in the report.
You should read Producing Reports Using LANSA in the Developers Guide before attempting to use a DEF_HEAD command.
