Keyword considerations for display files that use DBCS

Some DDS keywords should be avoided in double-byte character set (DBCS) data fields, and others should be 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)
