#include <graphics.h> void outtext(char *textstring);
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.
