Dear All,
I am an amateur in PERL trying to write a script for matching elements of array but there is slight glitch... Please help me.
I have one file consisting of ids... The other file consisting of ids and a sequence of letters associated with those ids.
eg. File A : 1DWK 2RFK 4ERH and so on...
File B: 1DWK
HRSDKKDAHJKLSDLDLLJDGHDFJJE
4ERH
DFSKFHADFSBVHFWIHFWJBFS
2RFK

I have written a script to match ids in both the files and return the ids with sequence as result:
#! usr/bin/perl
#this script is to match the two files and print the matched content i
+n the two files 
$p="FILEA";                           
open (FILE1,$p);

@array =<FILE1>;
#print "@array";
$p1="FILEB";                        
open (FILE2,$p1);

@new = <FILE2>;

#print "@new";
foreach $line (@array)
{

chomp $line;
open (OUT,">nrset.txt");
for($i=0;$i<@new;$i++)
 {
   chomp $new[$i];
 #  print "$new[$i]\n";

   if ($new[$i]  =~ /$line/i)

      {
        $pos = $i;
         print "$pos\n"; 
      
 
 print OUT "$new[$i]\n$new[$i+1]\n";
# print  "$new[$i]\n$new[$i+1]\n";
}
}}

This script just runs creating a nrset.txt file which is empty but doesn't show any matches. While I supposed my File having ids with sequence is too huge, tried to take few checkfiles which gave expected results as my script should do. Help me fellas!
Thnx in adv.
