YESNO

 Function
  Set the international yes/no response flag in an INPUTSTR or PROMPTSTR
  statement.

 Value
  16384 = 100000000000000b = 40000o = 4000h

 Remarks
  The INPUTSTR and PROMPTSTR statements have the ability to allow a yes/no
  response to be entered in addition to any valid characters passed to the
  statement.  The extra characters allowed are Y/N (or whatever characters
  were defined for the current language; spanish would use S/N, french
  would use O/N, etc).  Note that you do not need to pass any valid
  characters to use this flag; regardless of the other legal characters
  the international Y/N characters will be allowed.

 Example

  STRING ans
  LET ans = NOCHAR()
  INPUTSTR "Run program now",ans,@X0E,1,"",AUTO+YESNO
  IF (ans = NOCHAR()) END
