I agree with your logic, John. A well-spoken and thoughtful reply.
I also used ALP for many years; back in the ‘dinosaur’ days before list boxes
were not even thought of. Seemed for many years 4D was content to leave that

I can't think of a single instance where iterating in reverse is even

collection of the ones you want to delete. If you do it right, that's

Hi Chris,
What we really need is a way to access a Form Object's "Variable or
Expression". There's a Command named "Object Get Data Source" which was
added in v14, but it only returns a Pointer if "Variable or Expression" is
a Variable. If it's an Expression it returns Nil.

single process variable, interprocess variable, or any other ‘vestiges’ of 4D

my feeling is that generic coding is very much possible in object notation,
but we need to accept that the approach is different.
if you prefer to use pointers such as "Self",
I think it's best to avoid object notation,
at least if your goal is to make the code generic.
it's not a defect of ob
*OBJECT Get pointer*(Object named;"")
does return the Form object.
If you standardise your naming convention of the form field objects you
could determine the sub object and attribute you're looking for.
example:

FormObj_Wrap_Trim:
$vT_Object:=*$1*
$vT

you can even go one further und just put all that into the form method:

Generic programming of vars on a form is very complicated when one uses object
