CASE-ELSE statement

The CASE–ELSE statement is a conditional expression very similar to IF–THEN–ELSE, except that it allows for more than two choices of outcomes for the evaluation of the controlling expression. The syntax of the CASE-ELSE statement is as follows:

CASE <ExpressionToBeEvaluated> OF
  <Value Set 1> : <Action Statement 1>;
  <Value Set 2> : <Action Statement 2>;
  <Value Set 3> : <Action Statement 3>;
  ...
  ...
  <Value Set n> : <Action Statement n>;
 [ELSE <Action Statement n + 1>;
END;

The ExpressionToBeEvaluated must not be a record. The data type of the Value Set must be capable of being automatically converted to the data type of the ExpressionToBeEvaluated. Each Value Set must be an expression, a set of values, or a range of values. The following example illustrates a typical instance of a CASE-ELSE statement:
