IsEmpty Function

Returns a Boolean value indicating whether a variable has been initialized.

IsEmpty(expression)

The required expression argument is an Object containing a numeric or string expression. However, because IsEmpty is used to determine if individual variables are initialized, the expression argument is most often a single variable name.

Remarks

IsEmpty returns True if the variable is uninitialized, or is explicitly set to Empty; otherwise, it returns False. False is always returned if expression contains more than one variable. IsEmpty only returns meaningful information for objects.
