But after using the code, I am getting only the first column, not the 2nd and third.

I am not sure what the problem is?

thanks in advanceSmilie

I just test the code using your sample data, it works fine, my guess is the format of files make you fail, so please run
Code:
 dos2unix file1 file2

first, then re-run the awk code, see if it work.

I tried that, but still not working. Your first code (for just 2 files)
Code:
awk '{if($1 in a){sub("0" FS,"",a[$1]);a[$1]=a[$1] FS $2}else{a[$1]="0" FS2}}END{for(i in a)print i,a[i]}'

works just fine if I use 2 files. But the 2nd code doesn't work.

Tha't weird, how about this?
Code:
awk 'FNR==1{t++}{a[t" "$1]=$2;b[$1]}END{for(i in b){printf i ;for(j=1;j<=t;j++)printf FS (length(a[j" "i])?a[j" "i]:"0");print ""}}'

or you can use "cat -A" to see if there're some weird word in your files.
