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.
next if ($lines eq $_);
$lines = $_;
here is the example data I'm using
G123456798 ignore this as this is the first instance of G record
G123456798 even though this is the same ignore as its first insta
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!!!
