How do I hop from updating or operating on one window to another?
The manual mentions window handles, and I have successfully gotten
info (e.g., position) on whichever window I choose - as refered to by
the corresponding handle). But the program always arrives at the LAST
window opened, and I cannot enter updated data read by an earlier
i/o window.

Soooo... how would I get back to a previously opened window (left
open) to enter new values for the input variables, so that they can
affect what is drawn in a graphics window that has also been left
open?

I understand about callback functions after plodding my way through
the ClearWin+ manual, but this handle thing has me stumped.

With many thanks,
Ludwig

There should not be an issue here.
The user selects a window and enters data. All you have to do is to put all of the resulting data in COMMON (say) and find a way in the program of detecting when the data has changed so that the changes can be applied. For simplicity you could present an "Apply" button.
