Yup, the amount of processing on this one is a real monster.
The app will convert a "fixed field" flat file into tab delimited
format, constructing a proper header, filtering out (deleting) the
items that are not required, adding decimals in the right position in
a couple of fields, then finally logically inserting dash(es) "-"  in
specific places, based on the length and content of each string
containing from 6 to 13 alphanumeric characters... all while
maintaining a copy of the original item number.

With all of the great assistance for making selective deletions, I
actually have the majority of it coded and functional. Still need to
do some fine tuning on the strategic/logical placement of dashes
though. This little puppy will run as slow as molasses, so thankfully
my client won't need to use it more than once per quarter.

Then I get to build a second version that keeps the deleted "F" items
in place while removing everything else.
Oh what a joy. ;-)

Thanks to all of you for the help... very much appreciated!
