Legacy Binary File Editor

Hi I was thinking, I've also use a simple Forth program to edit some binary files that needed incemental edits and sometimes changes backed out. I wrote simple words to change data at offsets so that I could replay them on an unaltered input file. I'd then write the new file out as it was being edited. I used other simple Forth programs to scan the files for particular parts of the code to look at and determine if they should be edited. I used this method on my Nictolet 1080's code. The only tapes I could find were for the hard disk versions. I wanted to run these on my Nicolet's floppy drive. I had to change buffer sizes and offsets for a number of programs that wrote to disk, like the editor, assembler and BASIC. I'd then pretended that my laptop was a serial paper tape reader and sent the tapes files to my Nicolet. I'd then copy the sectors to the drives. This was all done within a relatively simple Forth program that I wrote. I did it this way so that I could easily change my mind about the values I used and it automatically kept a record of exactly what and where changes were made, since these were just part of the Forth program I loaded.
