Code:
#! /bin/perl
open(IDX,"<Index") || die "Couldn't open index file";
@index=<IDX>;
close IDX;
$header{POSITION}="Position";
for($i=0;$i<$#ARGV+1;$i++)
{
$FH="F${i}";
open($FH,"< $ARGV[${i}]") || die "couldn't open $ARGV[${i}]";
$header{POSITION}="$header{POSITION} $ARGV[${i}]";
while(<$FH>){
chomp($_);
@array=split(/  */);
foreach $index (@index){
if($index==$array[1]){
chomp($index);
$hash{$index}="$hash{$index} $array[3] $array[5]";
}
}
}
close $FH;
}
print $header{POSITION}."\n";
foreach $item (keys %hash){
print "$item $hash{$item}"."\n";
}

Have index file named as Index in your executing directory and execute the above as
Code:
perl anyname.pl file1 file2

I see your code has good elements..you can use my logic and improve the script a lot...you can reduce the script make it less complex etc...left to you...

and while splitting the fields, i observe you have used tab delimiter...i have used space...so take care of that..

locale::codes::langfam

Locale::Codes::LangFam(3)				User Contributed Perl Documentation				 Locale::Codes::LangFam(3)

NAME

       Locale::Codes::LangFam - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangFam;

	  $lext = code2langfam('apa');		       # $lext gets 'Apache languages'
	  $code = langfam2code('Apache languages');    # $code gets 'apa'

	  @codes   = all_langfam_codes();
	  @names   = all_langfam_names();

DESCRIPTION

       The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in
       ISO 639-5.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5
       language family codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a
       constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lext = code2langfam('apa','alpha');
	  $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages.

	   This is the default code set.

ROUTINES

       code2langfam ( CODE [,CODESET] )
       langfam2code ( NAME [,CODESET] )
       langfam_code2code ( CODE ,CODESET ,CODESET2 )
       all_langfam_codes ( [CODESET] )
       all_langfam_names ( [CODESET] )
       Locale::Codes::LangFam::rename_langfam  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangFam::add_langfam  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangFam::delete_langfam  ( CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangFam::delete_langfam_alias  ( NAME )
       Locale::Codes::LangFam::rename_langfam_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::delete_langfam_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
