I just discovered Prima and am having great fun with
it. Since I know little OOP, I began playing with the
sample Image Viewer app in the VB and in short order
added "zoom in/out" buttons and a "save file" option.
Also got the InputLine to send any changes to a Label
widget I added to the Form.

But now I'm stuck: In a new application, I want to
store changes to one or more InputLines in some data
structures (array or hash) . At some point, I would do
some operations on this and then save the results to a
file, manipulate them in some way, or pass them to
another widget. But I can't get it to work with even
one InputLine and a simple array @textlines.

If I define the array anywhere but in the event
('InputLine1' =>OnKeyUp) where I push data into it, I
get a "Can't call method "execute" on an undefined
value" when I run the app. If I define the array in
the event where I add the data, no error but it only
stores that one piece of data.

Any suggestions would be appreciated.
