DDS Positional Entry Considerations

The following section describes, by position, DDS for describing display files. Positions not mentioned have no special considerations for UCS-2 Level 1.

DDS Length (Positions 30 through 34)

Specify the length of the field in these positions. The length of a field containing UCS-2 Level 1 data can range from 1 through 16 381 bytes.

When determining the program length of a field containing UCS-2 Level 1 data, consider the following:

DDS Data Type (Position 35)

The only valid data type for UCS-2 Level 1 data is the G data type.

G (Graphic)
Type G in combination with the CCSID keyword to specify this field contains UCS-2 Level 1 data.

Normally, by specifying G, the field would contain graphic-DBCS data. In combination with the CCSID keyword, the field now contains UCS-2 Level 1 data. On output, the data is mapped to corresponding characters in the CCSID that the device is configured as. On input, the data is mapped to corresponding UCS-2 Level 1 characters.

DDS Decimal Positions (Positions 36 and 37)

Leave these positions blank when using UCS-2 Level 1 data.

DDS Keyword Considerations (Positions 45 through 80)

The DFT keyword may contain SBCS, bracketed-DBCS, or bracketed-DBCS-graphic character strings when specified on a UCS-2 capable field.

No validity checking is allowed on a UCS-2 capable field.
