 +====Syntax of outtextxy ==== 
 + <code c>
 +#include <graphics.h>
 +void outtextxy(int x, int y, char *textstring);
 +  </code>
 +
 +
 +==== Description of outtextxy ==== 
 +<code c>
 +outtextxy displays a text string in the viewport at the given position
 +(x, y), using the current justification settings and the current font,
 +direction, and size.
 +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 or outtextxy,
 +any part of the string that extends outside the current viewport is
 +truncated.
 +outtextxy is for use in graphics mode; it will not work in text mode.
