IsArray Function
Returns a Boolean value indicating whether a variable is an array.
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".
