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:
|
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 for more details about DDS Data Type/Keyboard Shift for display files (Position 35).
