Problem will occur on reread after 64k/78(ll) *16 (bytes per line) of
input, so max com file that can be reconstructed with this code is ~12k.

Why not post the source code? It's easier than entering text directly
into debug (if that is indeed what you're doing).

Needed extra code taking it beyond 80h bytes, so I added some help in.
tested OK on reconstructing a 143k text dump back to 40k

I don't begrudge people their hobbies. HEX code used to be
distributed in physical DOS magazines now and then. I think
I only encountered it once, and managed to type it and and get
it to work. Unfortunately, I had no idea how to learn any of
it, because I was a country boy and didn't have access to a
good library with DOS programming books.
