FUNCTION:
_ReColor( nFRow, nFCol, nTRow, nTCol, cColor) --> NIL
PARAMETERS:
nFRow : Screen area coordinates
nFCol : ""
nTRow : ""
nTCol : ""
cColor : Color to rewrite region in
SHORT:
Rewrite screen region in different color, leaving text intact.
DESCRIPTION:
_ReColor() redraws a screen region in a different color leaving the text
there intact.
Since the only "default" color would be the current color, there is not
much sense in not specifying it. However, if cString is not specified,
the default is in fact the current color setting.
If any of the screen area coordinates are not specified, the function
does nothing and immediately returns NIL.
NOTE:
This function is the opposite of _ColorSay() which writes text on the
screen in the colors already there.
EXAMPLE:
_ReColor(5,10,7,40,"W*+/R")
Result: Whatever is currently in the area of the screen at the given
coordinates is rewritten in blinking high white on a red background.
