Predefined Byte-Like Types

The data objects of the byte-like data types are used to include byte strings.

Attributes

Type	Length	Standard Length	Name
x	1 to 524,287 bytes	1 byte	Byte field
xstring	Variable		Byte string

Value Ranges and Initial Values

Type	Value Range	Initial Value
x	Any byte values, hexadecimal 00 to FF	Hexadecimal 00
xstring	As for type x	Empty string with length 0

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.

• The system class CL_ABAP_ELEMDESCR contains a constant TYPE_X_MAX_LENGTH for the maximum length of the type x.

• The maximum size of strings must be respected.
