Hex Editor for VMS?

[William John Pisciella]

I trying to find a hex editor for VMS that can simply edit a file and
change a couple bytes in it. Does such an editor exist either in the
operating system itself or in the public domain? We have a couple of
corrupted data files that have to be restored using several existing files
by taking chunks of data out of each and creating the new file (the
record format of all these files is the same). I've spent a week
looking but did not find anything. There must a something similar to a
hex editor out there somewhere! Any pointers or references will be
greatly appreciated. Please reply directly and I'll summarize.

The VFE utility by Ward Condit, Maricopa Community Colleges, can do what
you ask for above. I have used this utility to edit chunks of data in
files, without having to write a specialized program.

From "The OpenVMS Software List II" posted monthly to comp.os.vms/INFO-VAX
by J.C. Higgins, VFE is available from the following:

VFE
Description: Virtual File Editor
Availability: vesta.sunquest.com (149.138.1.42)
Filename: [.vaxvms.vfe]
Date: 4-Dec-1992

About VFE:

VFE is a block-oriented, type insensitive VMS file editor. It
can edit user files, FOREIGN-mounted tapes, and disk devices. Data
can be displayed in ASCII, EBCDIC, hex, binary, and integer format.
User-defined sections of single or multiple contiguous blocks can be
changed, compared, and transferred within a file or between files.
VFE also has a very fast search which can target a string, hex or
integer constant. All or part of a terminal session can be logged
to a sequential file for later lineprinter output.
