Notes

The byte-like data types are used for byte string processing .

The type x , for which a length interval is specified in the second column in the first table, is

generic , which means that the length is not part of the type description. The entry in the Standard Length column specifies the length used in declarations of data objects when using types with generic lengths, if no explicit length is specified in the relevant statement.
