12-1: Definition of Sets in SIMSCRIPT

Question: What is set and how sets are defined in SIMSCRIPT? (’97,’01)

Answer: Sets in SIMSCRIPT language provide a higher level of structuring of entities and their attributes. Sets are organized collections of entities. Set elements can identified and manipulated separately. The organization of entities in sets may be dynamic and changeable.

Sets can be defined with subscripts. Without a subscript, the set is declared as belonging to the system, using the statement

THE SYSTEM OWNS A set

A single-subscripted set definition associates one set with every member of some entity. The association is made in the EVERY statement defining the attributes of the entity type, in the following manner:

EVERY entity OWNS A set AND HAS AN attribute

For sets having the more than one subscript, a compound entity is defined, naming the set and the two or more permanent entities on which it is based. For example,

EVERY HUSBAND AND WIFE OWNS A FAMILY
