find records within certain parameters

[vidmo]

Hi, I am trying to smooth out some data. I have a long file formatted with position and signal strength:

22.38762 55.43485 107.333
22.3878 55.43485 94.0333
22.38797 55.43487 83.1333
22.38875 55.435 86.2666
22.38895 55.435 93.2999

I want to go through each line and find all other records in the same file within 0.001 of the position ($1 and $2), and then print the single position with the results (just $3) printed as subsequent fields:

22.38762 55.43485 107.333 101.3 106.8 204.9
22.3878 55.43485 94.0333 95.02 83.7

hope you can help me with this problem.

thanks

ok, i think i may have found a long winded way of doing this by producing a file of variables:
var1=12.38762
var2=12.3878
var3=12.38797
var4=12.38875
var5=12.38895
var6=12.38915

however i am having trouble feeding this variable into awk.
command check produces:
echo $var1
12.38762
echo $var2
12.3878

however:
awk 'NR==FNR{print NR, $"var"NR;next}' del.tmp
produces:
1 12.38762 45.43484 107.3331
2 12.3878 45.43485 94.03332

so i can see that NR is progressing but it is printing out the whole line in del.tmp instead of just the outside variable??

help!!!
