OK. Thanks. That will be more portable than return since objpas is
fairly common. Return is a bit simpler syntactically but exit
performs the same way which is more important to having to change or

It may help newcomers like myself if this was mentioned on the ref

Where/why would one use a typed constant vs. a variable. i.e.
const
myConst : double = 2.0*Pi;
var
myVar : double = 2.0*Pi;
It seems to me the typed constant is superfluous and can potentially
lead to bugs.

The sample code in the ref document doesn't document the simplest
case, but goes over what I think is a more complex example of a unit
that uses another unit.
It also doesn't have any actual code to do anything, so it is kind of
an abstract example . I

I am a little bit unclear about certain things on class constructors

From what I read in the language reference guide (chapter 6) and
runtime utilities document (chapter 29):
