IsArray function
Returns a Boolean value that indicates whether a variable is an array.
Grammar
IsArray (varname)
The varname parameter can be any variable.
Description
If the variable is an array, the IsArray function returns TRUE, otherwise the function returns FALSE. Using the IsArray function works well when a variable contains an array.
Example:
<%
Dim A (10)
For i= 1 to 10
A (i) =i
Next
Response.Write (IsArray (a))

%>
The result is: true

This function is used relatively little. It would be nice to know that there was a function.
