Constants are identifiers that have a defined value that cannot be changed in DGL statements.
The keyword CONSTANT appears only once in the declaration section, before the data-type assignments for constants. Each data-type statement may be followed by as many identifiers of the same type as you want to define.
As many type statements as desired may follow the CONSTANT keyword.
The constant type may not be a Statemate element, or a list of type.
The identifiers in the CONSTANT statement must have their values assigned in the statement. The value may be any expression not containing variables or parameters.
