Keyword considerations for display files that use DBCS

Some DDS keywords should be avoided in DBCS data fields, and others used with caution.

Do not use the following DDS keywords with DBCS data fields (the data type specified in position 35 is J, E, O, or G):

AUTO(RAZ)
BLKFOLD
CHECK(M10)
CHECK(M10F)
CHECK(M11)
CHECK(M11F)
CHECK(RL)
CHECK(RLTB)
CHECK(RZ)

CHECK(VN)
CHECK(VNE)
CHRID
DATE
DLTEDT
DSPATR(OID)
DSPATR(SP)
EDTCDE
EDTWRD

FLTFIXDEC
FLTPCN
MSGCON
REFSHIFT
SFLMSGKEY
SFLPGMQ
SFLRCDNBR
SFLROLVAL
TIME

Do not use the CHECK(LC) and LOWER keywords on DBCS-only fields (J specified in position 35).

Do not use the IGCALTTYP, IGCANKCNV, CHECK(LC), and LOWER keywords on DBCS-graphic fields (G specified in position 35).

The following DDS keywords can be used in files containing DBCS data only when the function indicated by the keyword is available on the display device or with the type of data used. However, DDS does not apply record- and file-level keywords to DBCS fields.

CHECK(RL)
CHECK(RLTB)
COLOR

DSPSIZ(*DS4)
DSPATR(SP™)
DSPMOD

ERASEINP(*ALL)
MDTOFF(*ALL)

CNTFLD (Continued-Entry Field) keyword
Use this field-level keyword to define a field as a continued entry field.
GRDATR (Grid Attribute) keyword
Use this file- or record-level keyword to define the default color and line type attributes for the grid structure.
GRDBOX (Grid Box) keyword
Use this record-level keyword to define the shape, positioning, and attributes for the box structure. This keyword defines whether the box is erased, displayed, or not processed.
GRDCLR (Grid Clear) keyword
Use this record-level keyword to define the rectangle on a screen in which all grid structures are cleared.
GRDLIN (Grid Line) keyword
Use this record-level keyword to define the shape, positioning, and attributes for the line structure. This keyword defines whether the line is erased, display, or not processed.
GRDRCD (Grid Record) keyword
Use this record-level keyword to define a grid line structure.
IGCALTTYP (Alternative Data Type) keyword
Specify this field-level keyword to change input- and output-capable alphanumeric character fields to DBCS fields with data type O.
IGCCNV (DBCS Conversion) keyword
This file-level keyword lets you use DBCS conversion, an alternative to directly typing in DBCS characters from a keyboard, in display files.
