WINDOW was Marinchip's screen editor, itself written in QBASIC. I wrote WINDOW originally to squelch the outcry from Marinchip customers for a ``screen editor''-something I believed at the time beneath real programmers. I named it WINDOW after the code name for radar chaff, a lightweight countermeasure that's all image and no substance. WINDOW was briefly marketed as AutoScreen for CP/M, and later its design served as the basis for the screen editing features of Kern Sibbald's editor.
