I was thinking about how to create a new parameter in a method, similar to Output or ByRef...

What documentation can I read to learn more about this?

I want to create a parameter customized.

 I am creating a class to validate JSON body of requests. When I use the method %ValidateObject to check errors in the object, if I define some properties with %DynamicObject or %DynamicArray and use the Required parameter, this method does not work, it ignores validation, only works with properties %String, %Integer etc.

Class test.

How to manipulate the code of the studio? Error messages, adding new items in the general options, formatting of the code, code typing...

Exist some command for return the quantity row of a global?

Example:

^test(1)="aa"
^test(2)="aa"
^test(3)="aa"
^test(4)="aa"
Total rows = 4
