another elegant solution... gotta admit i had to
read that one a couple times to 'catch it'...heh

well, the plot() function doesn't exist as a
standard euphoria function, it would have
to be made.  I was just trying to provide
an inherently intuitive pseudo-function that
all of us would immediately know what the
function did. to specify:
   procedure plot(sequence x, sequence y, atom clr)
   --assumes x & y are both equal length sequences
   --containing valid points on the user graphic screen
   --note: this is prolly not the best implementation of
   --      this function...
        for index = 1 to length(x) do
                pixel(clr,{x[index],y[index])
        end for
   end procedure

> The function allfalse()
function allfalse(sequence conditions)
   return not find(TRUE,conditions)
end function

don't get that one... :(

take care all, and hope you get back online carl--Hawke'
