None

Syntax

None(fieldlist)

where fieldlist is an arbitrary-length list of fields in the form:

[recordname.]fieldname1 [, [recordname.]fieldname2] ...

Description

The None function takes an arbitrary number of field names as parameters and tests for values. None returns True if none of the specified fields contain a value. It returns False if any one of the fields contains a value.

A blank character field, or a zero (0) numeric value in a required numeric field is considered a null value.
