     This package of procedures implements a subset of the ANSI terminal
  control sequences.  The names of the procedures are taken directly from
  the ANSI names.  If it is necessary to use these routines with non-ANSI
  devices, link in iolib.icn, and (optionally) iscreen.icn as well.  Use
  will be made of whatever routines are made available via either of these
  libraries.  Be careful of naming conflicts if you link in iscreen.icn.
  It contains procedures like "clear" and "boldface."

	 CUB(i)		Moves the cursor left i columns
	 CUD(i)		Moves the cursor down i rows
	 CUF(i)		Moves the cursor right i columns
	 CUP(i,j)	Moves the cursor to row i, column j
	 CUU(i)		Moves the cursor up i rows
	 ED(i)		Erases screen: i = 0, cursor to end; i = 1,
			   beginning to cursor; i = 2, all (default 2)
	 EL(i)		Erases data in cursor row: i = 0, cursor to
			   end; i = 1, beginning to cursor; i = 2, all
			   (default 0)
	 SGR(i)		Sets video attributes: 0 = off; 1 = bold; 4 =
			   underscore; 5 = blink; 7 = reverse (default
			   0)	

     Note that not all so-called ANSI terminals support every ANSI
  screen control sequence - not even the limited subset included in
  this file.

     If you plan on using these routines with non-ANSI magic-cookie
  terminals (e.g. a Wyse-50) then it is strongly recommended that you
  link in iolib or itlib *and* iscreen (not just iolib or itlib by
  itself).  The routines WILL WORK with most magic cookie terminals;
  they just don't always get all the modes displayed (because they
  are basically too busy erasing the cookies).
