 +==== Description of outtext ==== 
 +<code c>
 +outtext displays a text string in the viewport, using the current font,
 +direction, and size.
 +outtext outputs textstring at the current position (CP). If the
 +horizontal text justification is LEFT_TEXT and the text direction is
 +HORIZ_DIR, the CP's x-coordinate is advanced by textwidth(textstring).
 +Otherwise, the CP remains unchanged.
 +To maintain code compatibility when using several fonts, use textwidth
 +and textheight to determine the dimensions of the string.
 +If a string is printed with the default font using outtext, any part of
 +the string that extends outside the current viewport is truncated.
 +outtext is for use in graphics mode; it will not work in text mode.
