A MacProlog32 program window can be manipulated in exactly the same manner as a normal
Macintosh window. To increase the size of a window, click on the size box in the bottom
right corner of the window and drag it down to the right. To reduce the size of the window
drag the size box to the left. The window size changes take effect when the mouse button is released.
To make the window zoom out to fill the screen, click on the zoom box which is on the
right hand corner of the title bar. Clicking on the zoom box again will make the
window return to its former size. To move a window, position the pointer anywhere on
the title bar of the window and drag it to the new position by holding the mouse
button down while moving the mouse.
While you can have many windows on your desktop at the same time, there can only be
one active window (indicated by the highlighted title bar). A window can be made active
by clicking anywhere within the window concerned. By clicking scroll arrows or dragging the
scroll box along the scroll bar on the right side of the window, you can move what is
displayed in the window. The position of the scroll box in the scroll bar indicates
the position of the displayed text relative to the entire window. A window can be closed
by clicking the close box on the left hand corner of the title bar.
