                            Small-Windows Version 1.1
         
         Small-Windows  is  a  library  of  windowing functions for the C
         language. It runs under PC/MS-DOS (version 2.1 and later) on IBM
         and compatible microcomputers. It supports  MDA,  CGA,  and  EGA
         video adaptors.
         
         As  its  name suggests, Small-Windows was originally written for
         use with the Small C compiler (as implemented on the IBM  PC  by
         J.  E.  Hendrix).  Small-  Windows  is a very complete windowing
         package, however, and  versions  for  Microsoft  C  (4.0,  5.0),
         Lattice  C  (3.0),  and  Turbo  C  (1.0) are also available. All
         source code is included.
         
         Four levels of  functions  are  included.  There  are  18  video
         functions,  41  window  functions,  7 menu functions, and a file
         directory facility. The video functions are  interfaces  to  the
         BIOS  and display memory. They are written in assembly langauge.
         For speed, display memory is accessed directly.  Retrace  timing
         is optional. Multiple video modes and pages are supported.
         
         The  window  functions  constitute the main body of the package.
         With them, you can define as many windows as memory will  allow.
         There  are  functions to clean, frame, move, hide, show, scroll,
         push,  and  pop  windows.  Cursor  position  and  size  may   be
         controlled.  Data  and/or  attributes can be written to windows.
         Window  versions  of  six  standard  I/O  functions   (including
         printf() and scanf()) are provided. Finally, there is a function
         for acquiring edited input from window fields.
         
         The  menu  functions  provide a wide range of menu capabilities.
         Both static and pop-up menus are supported. Menu shapes  may  be
         rectangular,  vertical,  horizontal,  or single-item. Frames and
         titles are optional. Scrolling gives access to  overflow  items.
         Sorting is provided for variable menu items.
         
         The  directory  facility  illustrates  the use of the window and
         menu functions  and  provides  a  very  useful  file  selection,
         renaming, and deletion capability.
         
         Two  test programs are provided for exercising the window, menu,
         and directory functions. They also provide further  examples  of
         using the library.
