[comp.sys.amiga.tech] Editing Binary Files

gksmith@watcgl.waterloo.edu (Gary Smith) (07/07/89)

Does anyone know of an editor which will allow me to modify bytes in a 
binary files?  For example, I would like to be able to replace a byte, whose
offset from the beginning of a file is phi, with a byte whose value is omega.
I am looking for something a little more fancy than this but the point should
be clear.

Thanks,
Gary.

Ps. Is it available on a Fish Disk.

For heavy binary mucking, I'm sure a sector-editor that knows about
files would be your best bet, but I'd like to recommend a good
solution for light editing.  I use a PD Strings program along with
CygnusEd Professional.  CED Pro isn't public domain, but it's a
bargain (it has the exact features I need, plus a zillion more, plus
it is uncrashable, plus an ARexx port).

So, if you're in the market for a good (commercial) text editor, but
want to do some binary editing every once in a while, I'd recommend
CygnusEd Pro and use the fact that it'll read a binary file (and let
you enter chars in decimal).

Re: editing binary files on the Amiga ...

Look for the program NewZAP (formerly FileZap) by John Hodgson.  It's in the
Fish Disk collection.  Latest version is, I believe, 3.1, but 3.0 works fine,
too.
