DDS for physical and logical files

Length (positions 30 through 34)

The length of a field containing bracketed-DBCS data can range from 4 through 32 766 bytes (4 through 32 740 bytes if the field is variable length). The length of a DBCS-graphic field can range from 1 through 16 383 characters (1 through 16 370 characters if the field is variable length).

When determining the length of a field containing DBCS data, consider the following:

For example, a bracketed-DBCS field that contains up to 3 DBCS characters, 1 shift-in character, and 1 shift-out character, has 8 bytes of data:

(3 characters x 2 bytes) + (shift-out + shift-in) = 8

A DBCS-graphic field that contains up to 3 DBCS characters has 6 bytes of data:

(3 characters x 2 bytes) = 6
