Syntax

IsArray(varname)

The varname argument can be any variable.

Remarks
IsArray returns True if the variable is an array; otherwise, it returns False. IsArray is especially useful with variants containing arrays.

The following example uses the IsArray function to test whether MyVariable is an array:

Dim MyVariable
Dim MyArray(3)
MyArray(0) = "Sunday"
MyArray(1) = "Monday"
MyArray(2) = "Tuesday"
MyVariable = IsArray(MyArray) ' MyVariable contains "True".
