To use the class concept you can create your class outside the VTL and release it as dll , then use a CreateObject method such as the following code

dim obj
set obj = createobject("dll.Yourclass")

And the Best way to use the Enum is by using constants , look to the following sample

Const dt_Nothing = Something
Const dt_Boolean = Something
Const dt_Decimal = Something
Const dt_Double = Something
Const dt_Integer = Something
Const dt_string = Something
Const dt_Array = Something
Const dt_NetJSON = Something

Hi sir,

I will try class concept. Thanks for your quick reply. But i have one issue. If we want to give dropdown options to user in a input box (when we take input from user at the time of attach the script) e.g symbol names in a dropdown. Then without enum how can we give it. Please guide me.

Thanks in advance.

For now you can't define the Enum datatype and as a workaround define each one to be a variable that can user set its value
