- If you want to do it by hand you could try BEAV. If you want
- to have some automated way of doing it you could write a macro
- in BEAV or write a C program. The following is my standard advertisment
- for BEAV;
-
- BEAV (Binary Editor And Viewer), is a full featured binary file
- editor. Just about any operation that you could want to do to a binary
- file is possible with BEAV. You can insert or delete in the middle of
- a file thereby changing it's size. You can edit multiple files in
- multiple windows and cut and paste between them. You can display and
- edit data in hex, octal, decimal, binary, ascii, or ebcdic formats. You
- can display data in byte, word, or long word formats in either Intel or
- Motorola byte ordering. You can send the formatted display mode to a
- file or printer.
-
- BEAV is based on the source for emacs for display and keyboard handling
- functions. The binary file handling and display formats are special
- to BEAV. There is a full manual included in this release. There
- are makefiles for unix, xenix 286, AmigaDOS, and MSC 5.1 under DOS. The
- old Wang PC is supported. This has been tested on 286 and 386 PC's under
- SCO UNIX and XENIX and AIX on a RS6000. There are a number of makefiles
- included, select the appropriate one and rename it to makefile.
-
- BEAV is available various archives, on WSMR-SIMTEL20.ARMY.MIL it is;

-
- Version 1.33 (8/9/92) of BEAV contains the following
- enhancements;
-
- * A new command, screen-rows, allows you to change the
- number of rows BEAV uses in the current screen. The command
- can be issued anytime, the current windows will be adjusted
- or killed as necessary.
-
- * Floating point numbers can be displayed.
-
- * BEAV uses the current screen color setting and does
- not change them on exiting. Thanks to Derek Millar,
- dmillar@ocf.berkeley.edu
-
- * The processing of the beavrc file has been enhanced
- to allow the processing of most commands.
-
- * The default key binding for "n-way-combine" command
- has been changed to ESC Ctl P. This makes ESC Ctl F
- available for the "display-float" command.
-
- * The copy-mark-to-cursor command would corrupt data if
- the region to be copied was greater than 4096 bytes. This
- is fixed.
-
- * The replace command would fail to find all occurances
- of a search pattern if the pattern fell on the boundary of
- certain internal data structures. This is fixed.
-
- * The memory used to handle screen images is now
- allocated at load time rather than staticaly allocated.
- This will allow systems with any screen size to be filled.
- This depends on the variable "nrow" being properly set by
- whatever terminal output file you have configured. The
- default for "nrow" is the #define "NROW" as set in the
- def.h file. The colunms remain fixed at 80.
-
- * Under Unix, BEAV will use the full screen as reported
- by the ioctl inquiry of the tty device. Previously, the
- bottom line was not used.
-
- * The prompt line is now erased properly.
-
- * Not new to this release, but important for foreign
- language users. All English text in BEAV is contained in
- the file "text.c". It should be relatively easy to
- translate and recompile. If someone wants to send me a
- translated version of "text.c", I will include it in my
- next release.
-
-
- I am willing to maintain BEAV and will entertain suggestions for
- modifications and/or bug fixes. I can be reached at;
