Hello Harold,

    as you also work with lighting, you got what I need. :)

    But it seens to me that those routines aren't exactly what I need.

    I have two values let's say that one is the CHANNEL and other is the
MASTER as in the lighting consoles. Both values can be anywhere from zero to
255 and the result is 8 bits also, from 0-255.

    The expression "RESULT = (CHANNEL * MASTER) / 255" is perfect. The
problem is that the execution time is very long.

    Some examples :
        X    Y    X*Y   /255   /256
        0  255      0      0      0
       48   47   2256      8      8
      200  199  39800    156    155
      210  210  44100    172    172
      220  221  48620    190    189
      230  230  52900    207    206
      255  255  65025    255    254

    If someone tell me a very fast way to make this I'll be eternally
grateful.

    Thanks,

    Brusque
