I have indexed text file with data as follows:

0 3051
1 0
2 0
3 0
4 0
5 0
6 0
7 0
8 0
9 0
10 10
11 1
12 25
13 1
14 1000
15 2
16 3
17 20
18 0
19 0
20 -49.73201

How can i change individual values without messing up the index number?

Thanks.

dim fso as object
set fso = createobject("scripting.filesystemobject")

dim ts as object
dim l as string
dim p() as string
dim d as string

set ts = fso.OpenTextstream("yourfile", 1)
while not ts.AtEndOfStream
  l = ts.readline
  p = split(l, " ")
  if p(0) = 15 then
    p(1) = 6
  end if
  d = d & join(p, " ") & vbcrlf
wend
ts.close
set ts = fso.OpenTextStream("yourfile", 2)
ts.write d
ts.close
