Name

IsEmpty Function

Syntax

IsEmpty(varname)
varname

Use: Required

Datatype: Variant

A numeric or string expression.

Return Value

Boolean (True or False).

Description

Determines if the variable has been initialized by having an initial value (other than Empty) assigned to it.

Rules at a Glance

  • If the variant passed to IsEmpty has been initialized, True is returned; otherwise, IsEmpty returns False.

  • Although IsEmpty can take an expression as the value of varname, it always returns False if more than one variable is used in the expression. IsEmpty is therefore most commonly used with single variables.
