what a funny way to use push and pop.
In TB this means quite something else.
After te card "whatever" is created, can I
use global variables from the main stack
and can I pop all data from the mainstack
into the various fields on that whateverCard?

I can give a viewer each dimension I want and I can
place it everywhere on the screen: a childviewer stays in the window,
a popupviewer has no limitationson the screen.

So what has happened now?

I am very sorry,but this goes beyond my imagination.
I am not revolutionary enough yet.

The scripting for a viewer is so easy, because every varaible
used in the script keeps its value when you start writing
the viewer part.
Example: in the script of button "store" of the intakeCard of
the main stack, I put all texts of the fields in a textline.
In the routine I showed in my last posting, I cab use the word
textline again !
But be aware that the viewer is for more than just adding a card:
everything you can do in the main stack, you can do in each stack
on your computer.
