Hi Kcott

I complete forgot about that thread, thank you for reminding me.

I do however have a quick question... if I want to check for duplicate G entries within the same scope (i.e between E and h records) how would I do it.

I have some example code I tried but it just prints all G records.

    my $lines

    if(/^G/)
        {
                next if ($lines eq $_);
                $lines = $_;
                print $_;
        }

here is the example data I'm using 
E123456789
G123456798      ignore this as this is the first instance of G record 
+in scope
h12345
E1234567
E7899874
G123456798      even though this is the same ignore as its first insta
+nce
G123456789      ignore this as it is different from previous G record
G123465798      should flag duplicate here because it is the same firs
+t G record in scope!!!
h1245
