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 maintain 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:

• Cannot be entered if a 1.2.7 Reference Field has been specified.

Tips & Techniques

• 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.

Platform Considerations

• 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).
