 C_XSHADOW()

 DESCRIPTION

 C_XSHADOW() draws a shadow around an object that is already
 displayed on the screen.  The function draws a non-destructive
 shadow so the characters on the screen, where the shadow is drawn,
 are not overwritten.  There are two types of shadows that can be
 specified which determine where the shadow appears around the object.

 SYNTAX

 C_XSHADOW(st_row, st_col, end_row, end_col [,type] [,color_code])

 PARAMETERS

 st_row (N), st_col (N), end_row (N), and end_col (N) define the
 upper left and lower right coordinates of the object on the screen
 to draw the shadow around.

 type (N) is the type indicator which determines the position of the
 shadow around the object.  If type is not specified, two (2) is
 used.  The shadow types are as follows:

 TYPE   SHADOW POSITION
 ----   ---------------
 1      Left side and bottom
 2      Right side and bottom

 color_code (N) is the numeric color code to draw the shadow.  Refer
 to Appendix E for a list of color codes.  If color is not
 specified, the default of black is used.

 RETURNS

 There is no return value.
