Set in Pascal is set of values ​​that have similarities - similarities in the nature, meaning that the same data type (nature) and the order of the writing does not have to be considered. Every object - the object in the set can be considered as members or elements of the set.

Example For Set :

Set the type of unstructured data contained in pascal, which is composed of several elements that have the same data type.

Set in pascal programming language similar to arrays in pasacl statement, SET is not only affected by the first element and the SET data type is no element with the same

Type variabel_of_set = SET OF tipe_data;

OR

Var variabel_of_set = SET OF tipe_data;

This is example using set in PASCAL

Example1 :
