Really stuck this time. I have a flat text file database ( reff.data ). The left side will always be different numbers while the right side may be repetitive. The simple part is I inject to the script a number From the left side and ask for the corresponding number on the right side. I inject the number as $line3 submitted from a form. 
$data_file="reff.data";
open(DAT, $data_file) || die("Could not open file!");
@raw_data=<DAT>;


@results = grep( /^$line[3]/, @raw_data);

foreach( @results ) {
    $record = $_;
     # strip the beginning key
    $record =~ s/^\d+//;
     print "$record";
}      
close(I);

Great this returns $record which will print out the number corresponding on the right. Now the difficult part. I now need to search the left side for that number and be given again the corresponding number on the right. I have tried the same search for the variable $record thus. 
$data_file="reff.data";
open(DAT, $data_file) || die("Could not open file!");
@raw_data=<DAT>;


@results = grep( /^$record/, @raw_data);

foreach( @results ) {
    $record2 = $_;
     # strip the beginning key
    $record2 =~ s/^\d+//;
     print "$record2";
}      
close(I);

But that printed out the whole database I can inject a number from the left and be given the Corresponding right. But then I need the script to go on and find that corresponding number in the left, and give again the corresponding right and so on and so on. I am not a module man but I have tried many things Some with surprising results However after being bogged down with this problem For about three months now, I really need to get past this and Soldier on . God bless Ye All…Nasa.
