Window size: The size of the visible part of the edit field (the window size) is determined by parameters `er3' and `ec3'. `er3' is # of lines and `ec3' # of columns. Example: er3=23 ec3=72 (traditional values) During a Survo session the window size can be changed by RESIZE <er3>,<ec3>. The physical size (fonts) and locaction of the Survo Main window is changed most conveniently by soft buttons SYSTEM -> WINDOW.
