Optional. If not specified defaults to either alpha (type A) or numeric (type P or S) system default values. Further information on input attributes is contained in DEFINE Parameters and OVERRIDE Parameters in the Technical Reference.

...

Optional. However, use of edit codes for all numeric fields (type S or P) is strongly recommended. Edit codes supported under this version of LANSA are shown in Standard Field Edit Codes in the Technical Reference Guide.

...

In other words, all field names and all alias names must form a unique list of names. The alias name facility is provided primarily for installations that use the COBOL or PL/1 programming languages. Refer to the specific IBM-supplied program reference manuals for the use of the ALIAS keyword. Name must conform to field naming conventions like the field name. COBOL or PL/1 language naming conventions are NOT checked.

...

Using *DIRECT has positive performance benefits, but when a prompting function is to be invoked this way it must use the FUNCTION OPTIONS(*DIRECT) command. Refer to CALL Comments / Warnings and FUNCTION Examples in the Technical Reference Guide for details of direct mode invocation of functions. A "prompt request" is made against a field when the user positions the screen cursor into a field, on its label, or on one of its column headings, and then uses the PROMPT function key. Normally the prompt function key is F4, but it may be assigned differently on your system.

...

If the reference field's prompt process/function is changed, any of the fields referring to it which have the same prompt process/function (before the referenced field is changed) also have their prompt process/function updated.

For technical details of Prompt_Key Processing please refer to the Technical Reference Guide. For examples of prompting processes and functions please refer to What Happens When the PROMPT Key is Used in the LANSA Application Design Guide.
