What's the easiest way to get rid of whitespaces at the end of a string of
text?
Thanks,
Brian

try this...
--------------
sequence text
for i = length(text) to 1 by -1 do
if text[i] != ' ' then
text = text[1 .. i]
exit
end if
if i = 1 then
text = ""
exit
end if
end for
-------------

Brian,
If whitespace consists of spaces only, then Derek suggestion is ok. If
it includes tabs, carriage returns and linefeeds, you will need
something like the function below.
jiri
function rtrim(sequence s)
-- discard trailing whitespace of sequence s
integer i
i = length(s)
while i do
if not find(s[i], {9,10,13,32}) then exit end if
i-=1
end while
return s[1..i]
end function
