THROUGH phrase

This specification applies to THROUGH phrases specified in the VALUE clause and the EVALUATE Statement.

A THROUGH phrase specifies a range of values, literal-1 through literal-2. The set of values included in the range is determined by the following rules:

1.	When the range of values is defined by numeric literals, the range of values includes literal-1, literal-2, and all algebraic values between literal-1 and literal-2.

2.	When the range of values is defined by alphanumeric or national literals, the range of values depends on the collating sequence used for evaluation of the range.

 

When the value of literal-1 is greater than the value of literal-2 in the collating sequence in effect at runtime, the Invalid Range exception condition is set to exist, and, upon completion of any exception processing, execution proceeds as if the range of values were empty.
