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:

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).
