1.2.13 Keyboard Shift

Specify the keyboard shift to limit what the user can type into a field.

Note - V11 SP5 onwards:

Keyboard Shift U is no longer an option. New Field Attribute SUNI indicates if a field is a Unicode field or not.
Keyboard shift settings can be changed and maintained via the LANSA Editor.

Valid keyboard shift values are based on 1.1 Field Types.

Rules

Allowable values are:

Keyboard shift	Meaning	Data Type Allowed
A	Alpha shift	Alpha
Blank		Alpha / Numeric
D	Digits only 0 - 9	Alpha/Numeric
I	Inhibit entry (no keyboard entry allowed)	Alpha/Numeric
M	Numeric keys	0 - 9, plus, minus, comma, dash, space, period
N	Numeric shift	Alpha / Numeric
S	Signed numeric	Numeric
W	Katakana (for Japan only)	Alpha
X	Alphabetic only	Alpha. A - Z, comma, period, dash, space
Y	Numeric only	Numeric

Additional rules are:

When using a DBCS LANSA language on DBCS operating systems, the IME mode is set dependent on the type of keyboard shift to allow the construction of DBCS characters from phonetics.
Keyboard Shift U is not valid for fields defined in functions. Therefore, any field definition commands that reference the original Other File field with Keyboard Shift U, must specify a valid value for the SHIFT parameter. Use SHIFT(*BLANKS) if users will only be entering SBCS data, otherwise set the SHIFT parameter to another appropriate value.

IBM i: The IBM i DBCS or IGC data types J, E & O have been implemented as the Alpha LANSA data type with LANSA keyboard shift J, E & O respectively.
J
Alpha, Used for DBCS only.
E
Alpha. Used for all DBCS characters or all SBCS characters. Both DBCS and SBCS are not allowed in the same field.
O
Alpha. Used for mixed DBCS and SBCS
IBM i: Refer to the IBM manual Data Description Specifications for more details about DDS Data Type/Keyboard Shift for display files (Position 35).

J	Alpha, Used for DBCS only.
E	Alpha. Used for all DBCS characters or all SBCS characters. Both DBCS and SBCS are not allowed in the same field.
O	Alpha. Used for mixed DBCS and SBCS
