Each form includes a Built-in parameter List named Default. The Default parameter List contains all of the form parameters that were defined in the form at design time. For example, if you define parameters p1, p2, and p3 in Form A at design time, they are automatically included in the Default parameter List for Form A.
/* Like any other parameter List, the Default parameter
** List can be passed to a called form by including it in
** the argument List of the OPEN_FORM, CALL_FORM, or
** NEW_FORM Built-in procedures.
