I Agree and like this

I don't see this being true. Enlighten me.

bmp = load_bitmap("my.bmp")
--errors not checked
pal = bmp[1]
bmp = bmp[2]
--Swap 8's with 128's
mask8 = (bmp = 8)
mask128 = (bmp = 128)
bmp -= mask8 *8 --0's the 8's
bmp -= mask128 * 128--0's the 128's
bmp += mask8 * 128 --adds the 128's where the 8's where
bmp += mask128 * 8 --adds the 8 where the 128's where
NO, that isn't used. but how about this one. Transparency.
Let's assume that 0 is the transparent color.
bg = background_area
bmp = transparency_bmp
mask = (bmp = 0)
mask *= bg
mask += bmp
display_image({0,0}, mask)
OR maybe this.
function find_all(sequence s, object x)
sequence result, mask
integer f
mask = (s = x)
result = {}
f = find(1, mask)
while (f) do
result &= f
mask[f] = 0
f = find(1, mask)
end while
return result
end function
data = "Contents of a 2 meg file"
answer = find_all(data, 0)
-- If anyone finds this function useful.
-- Simply state it here.
-- I want your votes as PROOF of argument to keep = as it is.
PS: I don't like equal() anymore than the next guy.
But, I'm one of those what was happy enough with compare()

Thus proving that people don't really read the prior posts in a thread.

3. Re: equal() and =
Sorry, but I'm not sure what that is suppose to me. If you mean that my
response is incorrect because he states STRINGS. Then I must ask. Did you
bother do continue reading to see where I supplied the find_all() function?
