I'm looking for advanced flat-file editing. Something that can read in a
file, and separate all fields whether fixed or variable length. Something
that can also line up all the fields, to be easily reviewed. The goal is also
to modify the data to set specific testing conditions. It would be great if
it would also bring in a file layout or data dictionary, and display the
names of the fields along with the values (on a record-by-record basis, or in
table format).

I just need it for flat files at this time.

Thanks.
