Hi all, The following code works prefectly fine, but it doesnt complete the job, gets through approx 98% then dies. The idea is attach to a file two columns of data that come from another file using an array (array size of 42000). NOt sure what the problem is, seeing that the array does hold all data? NOt sure if a hash approach is more suitable....but i am a novice with hashs!

 while (<FILE2>) {

    push @col, $_ =~ m/(\S+\s+\S+)/ #unless m/SN\b.*|generated\b.*|No\
+b.*|startpattern.*|endpattern.*/;
}

     
open(data, "<TRUE_OUTPUTS");
while(<data>) {

      $_ =~ s/^(\S\s+\S)/$1 $col[$i++]/;


     print OUT2 $_;
}

sample input:
0  1
0  1 
1  0

sample to attach:
0.85 0.20
0.65 0.50
0.23 0.48

output:
0  1 0.85 0.20
0  1 0.65 0.50
1  0 0.23 0.48

thanks
