### High

#### Synopsis

function High (`ordinal_type_or_variable`): `ordinal_type`;

or

function High (`array_type_or_variable`): `array_index_type`;

or

function High (`string_variable`): Integer;

#### Description

For ordinal types or variables of that type, High returns the
highest value a variable of that type can assume.

For array types or variables of that type, High returns the
highest index a variable of that type can assume. Note: the result is of
the same type as the array index is. If the array has more than one
dimension, High returns the highest index in the first dimension.

If the argument is a string variable, High returns the
discriminant of the string type (i.e. its capacity).

#### Conforming to

High is a Borland Pascal extension.

#### Example

program HighDemo;
type
Colors = (Red, Green, Blue);
var
Col: array [Colors] of (Love, Hope, Faithfulness);
Foo: Colors;
Bar: Integer;
Baz: String (123);
begin
Foo := High (Col); { yields Blue }
Bar := Ord (High (Col[Foo])); { yields Ord (Faithfulness), i.e., 2 }
Bar := High (Integer); { highest possible value of `Integer' }
Bar := High (Baz) { returns 123 }
end.
