  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

Perl-style or to select values. Rather than FileMaker's native C-style "or", which casts values to binary for evaluation, || treats non-zero, non-empty values as truth and returns these true values as the result of the expression. This is particularly useful for falling back to defaults values.
