And then there is/was the idea with: getting data on request.

Creating a list of objects for all the fields of a class, needs to be 
Well it is, by means of flags passed to Pascalbuilder.

What is missing, is the ability to later upgrade. There are 2 
1) re-reading target mem.
There already is a cache for target mem.
If TFpValue and TPascalBuilder are hold by a "watch value class", this 
can control the cache, and keep the memory.
This memory is only the class. Vaules by ref, like strings are not included.

2) adding list of fields, to watch that was text only
This will also rebuild the text. That can be suppressed, if needed....
