String data types (STRING, RAWSTRING) possess an unlimited length.

However, you can specify a length in the dictionary (at least 256 char.) . This length is taken as basis for optimizations when string fields are written to the database. From a certain length onwards, there are no further optimizations possible. Therefore, the length specification can be omitted (length 0).

If length 0 ist specified in the dictionary, no optimization is carried out during the storage on the database and an unlimited length is assumed.

Hello,

The predefined data types string and xstring describe data objects of variable length (dynamic data objects). While the length of data objects in all other elementary data types is determined for its whole lifetime, the length of text and byte strings varies according to their content (the maximum size of a string is determined by profile parameter ztta/max_memreq_MB, see Maximum size of dynamic data objects).

Hi,

Length of the string and xstring are variable initially length is 0 Then the value varies depending on the content they hold during the runtime.

string is a sequence of type C

xstring is sequence of bytes type X
