In exceptional cases there may be parameters to determine where the window
should appear. There may also be a parameter, which determines if the position is
relative to the module or to the screen.
Window positioning should be as follows: parameters to the right, trim curve to the
left, and bar graph beneath the interaction window.

All interaction windows shall have equally high texts, regardless of the window size.
To achieve this, the width of the control module that represents the interaction
window has to be proportional to the width of the interaction window according to
the following table:
In some cases several input fields in an interaction window are logically connected
to each other. Examples are option buttons where one and only one alternative in a
group of alternatives is selected. The grouping should be done with a rectangle
(similar to the ActiveX control Frame in standard MS-Windows programming)
around the interaction fields in question. Use window background (-2) for the frame
caption text to obtain look similar to a Frame ActiveX control. Note that it is
