Hi Jim,
Perhaps nearest should be the key. How I'm thinking is that as the files are looping the nearest match can be found and that is the one to use.
So $2 on file one has a number of 53.728563 and the nearest match on $2 on file two is 53.78.
Once that number has been found then loop though $3 on both files, but only look at the 53.78 numbers (the number we found on $2) there will be quite a few on file 2 and return then nearest match which would be -2.44 and print out the rest..........
I dont think I'm making this sound easy am I? But please stay with me on this :-)
Cheers,
Ian

Hang on.....I will try and explain this again..
If I have one file called A.txt with
1
2
3
4
5
And I have another with
1.1
2.1
1.3
5.1
0.9
Is it possible to return a output file like this
1 0.9
1 1.1
1 1.3
2 2.1
5 5.1
As you can see I have matched up the nearest number from one file to another... I'm not sure whether this is possible to do, but this is what I desire :-)
Many thanks for looking at this
Cheers,
Ian

ing direction is to nearest with ties awary from zero, returns the same value as
