Andy,

Well, on the one hand it's your routine, so you should know, but on the
other hand, my test results show it does replace one with two.  Maybe
there's something wrong with my test??  I'll send you another copy of the
zip of the test I applied (previously sent twice to the forum), but here's
the pertinent variables, & a copy of one line of the results (the fact that
it says "Replace_in_string" instead of "replace_in_string" is just to
distinguish two different routines with the same name in the test, the one
with "R" is yours):


<code snippet>
integer tr  -- test repetitions
sequence r, rb  -- replace, replace by
text = {}
new = {}
times = {}

r = {')'}         -- replace
rb = {"ZZ"}   --replace by

tr = 5000  -- number of test repetitions


<snip code>

for n = 1 to tr do
new = Replace_in_string(text, r, rb)
end for

<code snippet ends>

Original line of text from a file (Henri's original offering):
       so = repeat(o, length(s)) -- here is the trick

Same line after output from your routine:
       so = repeat(o, length(sZZZZ -- here is the trick
