  The following Clipper functions have been changed as
  indicated.
  
  MAXROW() and MAXCOL() return values which depend on the size
  of the window currently selected.
  
  Of the vast number of Clipper commands, functions and
  statements, a few are not supported: FKLABEL(), FKMAX(), SET
  TYPEAHEAD, KEYBOARD(), CLEAR TYPEAHEAD,  SETCANCEL(),
  SETBLINK(), ALTD(), NOSNOW(), SETMODE(), DISPBEGIN(),
  DISPEND().
  
  Note that it would be contrary to normal Windows rules to
  allow CLEAR TYPEAHEAD (although you could implement it, if you
  insist, by just emptying the event queue).  NOSNOW() makes no
  sense, and is not required under Windows.  SETMODE() is too
  limited and does not make sense, given that users should be
  able to re-size a window as they see fit.  The DISPBEGIN()
  and DISPEND() functions are typically used to buffer screen
  updates, or in conjunction with SAVESCREEN() and RESTSCREEN().
  Windows does its own buffering of updates transparently to
  your program; SAVESCREEN() and RESTSCREEN() are mentioned
  below.
  
  The following look rather ugly, but do work (although previous
  versions of this document have said they did not): MENU TO,
  SET WRAP, ACHOICE(), MEMOEDIT(), SET FUNCTION, SET KEY, SET
  SCOREBOARD (which is best OFF).  There are Windows-like
  replacements for ACHOICE() and MEMOEDIT(), if you want to
  use them (see achoice.prg and memoedit.prg).
  
  These can be used, although you should not rely on them too
  much: SETCURSOR(), SET CURSOR, MEMORY().  The undocumented
  return values from MEMORY() are not guaranteed.  Clip-4-Win
  uses memory from Windows directly, so EMS memory is not
  required or used.
  
  RUN is not supported; use the WinExec() function instead.
  Also, DBEDIT() is not supported; use TBrowse() instead.
  
  SAVESCREEN(), RESTSCREEN(), SAVE SCREEN, RESTORE SCREEN are
  not supported.  Apart from the size that a window can be (over
  250K is common), there are Windows functions that should be
  used instead.  For example, use CreateWindow() when you want
  a new window.
  
  ALERT() automatically produces a modal dialog box.  You can
  use an ampersand ("&") before any letter you would like to be
  an accelerator key; the letter will then be underlined.  By
  default, the first letter of each choice is made an accelerator.
  (The source is in alert.prg.)
