[Pythoncard-users] Alternative to the Notebook

[jamesr <cir...@gm...>]

I was perhaps not specific enough in that I would like a volunteer or
two to experient with the framework i have, and report to the list in
general as to your opinion of it. It represents the (text only)
portion of a standard way of laying out python card program that would
be created and edited in a gui framework (!) in a future iteration.
the setup allows for a clean seperation of different gui elements and
it is especially for a code generation developemtn environment that
attaches python code to the larger strucuture sensibly. Any one with
experience in python card and is willing to listen to <5 minutes of
explanation would suffice.

At this point i think having some peer-review is my only chance to
have such a setup realistially considered by the group. Please email
cir...@gm... if you will beta test.

I appreciate the support, 
James.
