  VPUTCHR

  .  Summary

  vputchr(int <chr>);

  .  Description

  The vputchr function is used to place a character on the screen at
  the current cursor position, specifying color information at the
  same time. <chr> is the character to place on the screen. the low
  byte contains the ASCII value for the character, while the second
  byte contains the color value. In general, a if 'c' is the charac-
  ter, and 'color' is the color to use, the proper value is obtained
  with the expression

       (c + color * 256)

  Possible colors are numbered as follows:

                      Black          00
                      Blue           01
                      Green          02
                      Cyan           03
                      Red            04
                      Magenta        05
                      Brown          06
                      Light Grey     07
                      Dark Grey      08
                      Light Blue     09
                      Light Green    10
                      Light Cyan     11
                      Light Red      12
                      Light Magenta  13
                      Yellow         14
                      White          15

  To obtain a color attribute value for a color combination, the for-
  mula is

       color attribute value =

             foreground color value + (16 * background color value)

  Therefore, a Yellow character on a Blue background would have a
  color attribute value of 30 (14 + (16 * 1)).

  .  Return Value

  None.

  .  Example

  // Place an inverse 'X' in the left top corner of the screen

  gotoxy(0, 0);
  vputchr('X' + 112 * 256);
