Example

The following mrScriptBasic example uses the VarTypeName function to determine the type of a variable:

Dim MyTest, MyVar

MyVar = 34
MyTest = VarTypeName(MyVar) ' Returns "Long"

MyVar = "Hullo"
MyTest = VarTypeName(MyVar) ' Returns "Text"

MyVar = {1, 2, 3, 4}
MyTest = VarTypeName(MyVar) ' Returns "Categorical"

Set MyVar = CreateObject("TOM.Document")
MyTest = VarTypeName(MyVar) ' Returns "Object"
MyTest = VarTypeName(MyVar, True) ' Returns "TomLib.Document"
