In VBS: use the split function to break the string into an array on
commas. If the array is not in order, you'd want to sort it. Then
simply iterate through the array. If the current element matches the
previous one, ignore it. If not, concatenate it to the result string.
(Watch out for the first element.)
There is a split method of the string object in JavaScript. You could
use that to start off the same process in that language.

If you do not want to sort,
but are content with th first occurrance,
this ASP jscript will do,
and is much faster than sorting:
s = "15,15,1,3,6,6,6,12,13,14,15,15"
a = s.split(',')
b = new Array()
r = ""
for (i=0;i<a.length;i++){
b[+a[i]] = a[i]
}
for (x in b){
r += x+','
}
r = r.substr(0,r.length-1)

For me to better understand the script I rewrote it in vbscript. Regular
expressions are amazing stuff!
mylist = "1,3,6,6,6,12,13,14,15,15,15,15"
mypattern = "(,\d+)(?=(,.*)*\1($|,))"
set re = createobject("VBScript.RegExp")
re.Global = true
re.pattern = mypattern
myresult = "Source: " & mylist & vbcrlf & _
"Pattern: " & mypattern & vbcrlf & _
"Result: " & re.replace(mylist,"") & vbcrlf & _
"Duplicates: " & vbcrlf
for each match in re.execute(mylist)
myresult = myresult & match & vbcrlf
next
wscript.echo myresult

You'll want to append a comma (,) to the beginning when performing the
match/replace, then remove the comma when outputting. This is so the first
number in the list can also participate in the matching. Add a "1" to the
list somewhere in the middle to see what I'm talking about. I agree, regular
expressions are pretty amazing.

Yes, I was puzzled by the leading comma. I was quite sure it served some
purpose but it didn't detect its need in my experiment.
