Memographic Monks,

I have 

@my_list = (3, 5, 2, 9);

for $i (0 ..$#my_list) {
   print $my_list[$i]."|";
}

[download]
outputs 
3529

[download]
If I change the print to 
   print $my_list[$i]."XX";

[download]
it outputs 
3XX5XX2XX9XX

[download]
If I change it to 
   print $my_list[$i]."|n";

[download]
it outputs 
3|n5|n2|n9|n

[download]
But it will not output 
3|5|2|9|

[download]
as I want. Not even if I try 
   print $my_list[$i]."\|";

[download]

I know, pipe, perl control character....what's the trick to get it to print what I want?

Thanks.

UPDATE

Aie - holiday Monday programming - ok, time to take my lumps -

the code I provided was a short form for the real code which was 

@my_list = (3, 5, 2, 9);

for $i (0 ..$#my_list) {
   ... a bunch of stuff...

   $my_id_list .= $my_list[$i]."|";

   ... a bunch more stuff...
}
print $my_id_list;

[download]
where more scanning the code revealed this helpful little line 
#trim trailing delimiter
$my_id_list =~ s/\|$//;

[download]
in ...a bunch more stuff..., which of course was the wrong place for it. Should'a been after the lop and before the print.

So, lessons #3,673,592 & #3,673,593: don't code half asleep on a holiday Monday; post real code or at least a sanitized version of it, not shortcuts.

Let the flagellation begin.
