VAXTPU SHIFT — VMS 5.2

 SHIFT

 Changes the relative position of text displayed in a window on the screen.
 The character position displayed in column 1 on the screen is shifted to
 right or left -- typically, to view text that is wider than the window.
 The shift applies to any buffer associated with the window specified.
 SHIFT optionally returns an integer (for use with other VAXTPU
 procedures).

 Syntax

    [integer2 :=] SHIFT (window, integer1)

 Parameters

    window     The window in which the shift is to occur.

    integer1   The number of columns to shift the text.  Positive values
               shift from right to left (so you can see text beyond the
               right edge of the window).  Negative values are from left to
               right (so you can can see text beyond the left edge of the
               window).  If you specify 0, no shift takes place and the
               screen is not repainted.  Otherwise, the screen is
               repainted.  If the first character in the line of text is
               already in column 1, using a negative value has no effect.

 Examples

 1.  SHIFT (main_window, +5);

     Shifts text displayed in main window five columns to the left.

 2.  SHIFT (main_window, -5);

     Shifts text displayed in the main window five columns to the right, as
     long as existing text is beyond column 1.
