OOPS! Sorry about that! I just forgot that at the time wrote that File
Search I modified graphics.e.  Here are the modifications:


global integer TextColor -- text_color last value
global integer BkColor   -- bk_color last value

TextColor =3D 7 -- default value
BkColor =3D 0   -- default value

global procedure text_color(color c)
-- set the foreground text color to c - text or graphics modes
-- add 16 to get blinking
    TextColor =3D c
    machine_proc(M_SET_T_COLOR, c)
end procedure

global procedure bk_color(color c)
-- set the background color to c - text or graphics modes
    BkColor =3D c
    machine_proc(M_SET_B_COLOR, c)
end procedure

This was done to enables me  to reset the color context when leaving
file search function. I like functions that restore the original context
on leaving.  But to restore original colors we need a mean to know their
origal values.

P.S. I will be more carefull to stick to originals includes next time.
