That’s after midnight for me. I’ll try to attend, but I might be in bed already.

This example does not avoid having to carefully name form objects and
the form object must have "matching" variable and object names: variable
entity.MyName with its object name of "MyName"

a_test (OBJECT Get name(Object current))

a dot notation source will return a Nil pointer, regardless of the name
matching or not.
If you are using matched names, you could use the following:

The pointer OBJECT Get name(Object current) is to the entity instead of the to
the entity attribute.
The field is eg, MyEntity.MyName, but the pointer to the form object ends up
being ->MyEntity

Indeed, if you are using a process or an IP variables to hold the entity (or
object for that matter), you will get a pointer to that variable. But if you
are using the Form.XXX notation and eliminate the use of process or IP
variables, the pointer always return Nil, so it's useless.

Is there a "Get edited text without having to type anything first" kind of

Does an entry area have an Object that contains its type and contents?

Sorry, Are you saying that you can get a valid pointer with Object get

I think the point of OBJECT NAMES is to also help with SHOW/HIDE objects on

The object name should not need to be exactly what the ‘Variable or expression’
is.
And besides, there would be quite a problem if the object

I thoroughly enjoy using object notation and the Form. object. That is why I
want a way to continue to use it to designate the data source of form objects.
I have read and re-read Keisuke’s comment, and there are aspects I do not
comprehend. I thought that the attachment between form object and

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.
