Field Object

Chameleon offers simple methods for accessing subfields in segment field scripts via the use of a field object. This section lists the methods that the field object supports and demonstrates how they can be used.

Field Object Methods/Properties
Field Object Usage Examples
Field Object Behavior in Parser Versions

There was an issue in Chameleon versions 4.5 and earlier, where outbound segment scripts were erroneously executed for every repeat of a field during message generation. In versions 5.0 and later, the outbound segment scripts are executed only once per field.

Also note that repeat_field(RepeatIndex) behaves differently between parser engine versions. For more information, see Field Object Behavior in Parser Versions.
