Set Type Definition
The declaration for a set type definition has the following syntax:
type type_name = set of type_definition;
Syntax Note:
1. Although set definitions are accepted by the preprocessor, no set variables can be used in EQUEL statements. As discussed in the section above on record declarations, set declarations are accepted only because all record components must be declared to EQUEL.
