#ObjectScript #Caché

How do you initialise a list of objects of a particular type?

I have tried the following code and I get an undefined when I try to insert.

I can do this and it works but I don't know if it is correct.

Is there any way to do something like this?

Set a= New list of Accciones()

Thank you.

You could try this

 #Dim a As List Of Acciones = ##class(%ListOfObjects).%New()

The #Dim is a precompiler directive and not a statement. Objectscript is a type-less language. The #dim directive only assigns a type to a variable which enables capabilities like Intellisense.

The Creation, with the %New(), that you do in the second method is necessary since the list object does not actually exist before that.
