I re-thought this.

integer a
 sequence newlist,found
  newlist={}
  found={}
 for loop=1 to length(urllist) do
   a=find(urllist[loop],found))
   if a=0 then
      found=append(found,urllist[loop])  
    -- newlist=append(newlist,urllist[loop])--you don't really need newlist
                                            --unless you are going to alter
   end if                                   --urllist[loop] before you add 
 end for                                    --it to your sequence.
 urllist=found
--now your list is free of duplicates--

for loop=1 to length(urllist) do
   if find(junk,urllist[loop]) then
     exit
   end if
end for
  urllist=urlist & {junk}

Kat, perhaps you could trap your program at some point when it has
created a duplicate, and create an ex.err or print() the values so
this (the above code misbehaving) can be reproduced?

When doing this sort of thing, I usually do this ...

 urltemp = upper(urllist)
 junk = trim(junk)
 found = find(upper(junk), urltemp)
 if not found then
    urllist = append(urllist, junk)
 end if

In other words, trim both data and do an case-insensitive search.

The find() function looks for a single element that exactly
matches the subject argument.

The match() function looks for a set of adjacent elements that
exactly matches all the elements in the subject argument.

To use match() in the way you have above might work better as ...

   if match(junk,urllist[loop]) = 1  and 
      length(junk) = length(urllist[loop]) then

in other words, ensure that if you get a match it starts
with the first character and is the same length. But that's
now equivalent to equal()! So it might be better to do ...

   if equal(junk,urllist[loop]) then

but if you are doing that, you may as well use find()
as it will work faster.

According to the files i printed out, the items were the same. But find() didn't
find them.

I had a client call once: "Your software quit working!"

Me: "Did it work yesterday?"

Client: "Yes"

Me: "Did you do anything on your computer since yesterday?"

Client: "No. Just cleaned out a bunch of useless files."

Me: "What were their names?"

Client: "I don't know!  Just a bunch of .dat and .exe stuff I never use.
You need to come fix this!"

Me: "I'll be right over. Get out your checkbook."

Next time they called, I was "out of the country" :)

That's exactly how a lot of my conversations go, except they say...

Client: "No. Nothing's changed at all whatsoever."

At this point, I have to tell them:

Me: "Software doesn't just stop working for no reason."

We later find that either 1) their application was upgraded, which
requires an update to our software as well, or 2) they upgraded their
version of Windows, which sometimes requires an upgrade of our software.

So much for "Nothing's changed at all whatsoever."

Like i said, no. The code is running as is *now*, looping thru the list and 
using match on each item in the list. I don't want to interrupt it and waste 
internet bandwidth on a test, in case someone is waiting on the results of the 
code run.

Sorry i sound so unreasonable, but i gave you the code i was using that 
didn't run, said i do not feel i can stop the code for tests, and it's running
with
match(). In the files i printed out of the repeats, Textpad's search function 
found the items find() didn't.

The code you posted was this...


found = 0
for loop = 1 to length(urllist) do
  if match(junk,urllist[loop]) then
     found = 1
     exit
   end if
 end for
 if not found then
   urllist = urllist & {junk}
  end if
--------------

Try this instead...

-------------
if not find(junk, urllist) then 
   urllist = urlist & {junk} 
end if
------------

I DID bloody change the code, i am not using find() anymore, i am using

I had a problem with find(). I reported it. I recoded the apps to use match(). 
Programs are now running fine, as of when i gave up on find() and began 
using match() and reported the problem here. My mistakes were reporting 
the problem here, and not saving the code and data that didn't run; but i was 
in a hurry (i noticed the dupes after 4 hrs of it running, which put me 4 hrs 
behind), and gave up on find() after 30 min or so, and simply over-wrote the 
bad code with something which works. As an aside, the person i was 
counting on to have working demo code for the data i obtained, hasn't written 
a line of code YET. So much for a tight schedule and being reliable. And i 
am am pretty sure i won't report any problems here again if i am in a hurry. 
This thread really takes the cake.

I just sent Derek a screen shot of how busy the computer is. At this time, i 
don't have any free cpu clocks, memory, or bandwidth to test anything. 
Unless i shut things down,, and become the person who isn't getting things 
done.

Listfilter blocked my reply to Pete Lomax. I'd prefer my answer be posted for 
equal time on the webpage, and sent in the listserv.

I don't see him going after Chris, who reported he also hasto change code to 
make find() work. Neither of us asked for any help. I have said for the entire 
duration of this thread that i was not going to make changes in code that 
was running fine. So think i am paranoid, or delusional, or anything you want, 
but get off my case. This week-long running idiotic thread that i didn't ask
for,
but everyone hasto get in on, leading up to Lomax's personal flaming at me, 
is ample evidence that i don't imagine the attacks.

Saints preserve us.

Kat, if there is a problem in find(), like you *CLAIM*, then surely to
god you would like it resolved?

I don't care anymore. I only reported it, in case someone else was 
logging
problems and cared. I moved on before i wrote the first email. I 
didn't ask for
any help.

I am aware that in your personal life, you ferverently believe that
everyone just shits on you for fun. But that is not in general the
case on this list is it? That is not the case, and you know that.
Fine, you want to claim *I* hate you or unfairly pick on you, no
problem - if you feel so, I can assure you it is not intentional - but
if you claim that everyone on this list just hates you, you need help.

If we can help, we will, but if you refuse to let us help, we can't.
(in various technical Euphoria-related problems, I mean)

I am aware that is really really patronising and rather shitty of me,
but I just don't know what else to say. It *is* meant to trigger a
reaction, but not meant to be offensive, my apologies for being
rather bad at this sort of thing...

My reaction is: answering this thread has taken too much time from
productive coding. I didn't ask for help. I'm sorry i reported a 
damned thing,
think as badly of me as you want, no arguement from me. I've tried being
nice, saying i am now using match() in that code, and it's working, 
and it
was working BEFORE i reported the bug (as i CLAIM). But why, after all 
the
emails, you decided to waste 3 paragraphs on making this personal, i 
dunno.

Kat,
getting as pissed as you are now.

This spits out one duplicate: DUP FOUND: http://www.ed.gov

Also, I noticed such things as:

"http:// www.buydirectory.com"  has an embedded space;
"http://www.hub..terc.edu"         2 periods in a row;
"http://www.iee org.uk"              has an embedded space;
"http://www.ipl,irg/reading/books" has an embedded comma

Sorry for the delay.  I was trying to come up with a solution that wouldn't 
take hours to run.
Please tell me if you want me to continue.
