Understanding named sets

A named set is a mutually exclusive process variable (string), either user or system defined, that is assigned an ordinal (numeric) value and can be selected from a list.

These named set strings become easily understandable choices (displayed in list format) for recipe authors and operators to use when setting values for phase parameters (input, report types, phase algorithm), Boolean operator messages, and phase logic failure messages. The named set string corresponds to the ordinal value that is used by the phase logic in the controller.

Typically, you use named sets when the recipe author or operator needs to specify an ingredient type. The operator or recipe author does not need to specify the numeric value required by the phase logic. They only need to select the appropriate ingredient name from the named set list.
