Derek, I hope your day improved after the correction flurry.  And
since your girls  beat our girls at netball again tonight, I had to
try a little harder to compensate. I think the simplified function
below is just marginally faster than yours. But do not lose any sleep
over it...

jiri


function jparse2(sequence s, sequence s1, sequence s2)
    -- replace every occurrence of s1 in s by s2
    -- case insensitive search
    sequence os,u,v
    integer i,j,m

    os = {}
    u = lower(s)
    v = lower(s1)
    m = length(s1)
    i = match(v, u)
    j = 1
    while i do
        os &= s[j..j+i-2] & s2
        j += i+m-1
        u = u[i+m..length(u)]
        i = match(v, u)
    end while
    return os & s[j..length(s)]
end function
