BEAV User Manual
shift is 0. For example, a double word at address 10 is made up
of the bytes at address 10, 11, 12, and 13. With a shift of 1
that double word would be made of bytes 11, 12, 13, and 14.
With a shift of 2 then bytes 12, 13, 14, and 15 would be used.
The maximum shift in word display mode is one and the maximum
shift in double word mode is three.
The buffer is in effect shifted toward the beginning of the
buffer with 1, 2, or 3 bytes becoming not visible. These bytes
are not lost, they become visible when the shift is set to zero.
This command cycles through all possible shift values. There is
no effect in any byte display mode or any text display mode.
3.6 Inserting and deleting
These commands are the core of BEAV. These commands allow
the buffer to be edited in a similar fashion to a text editor.
BEAV has an insert mode much the same as text editors but it only
works when displaying data in one of the text modes, either ASCII
or EBCDIC. In other modes it doesn't make any sense to insert
characters as they are typed when there is more than one
characters per unit. In the data modes there is a command that
inserts a unit of zeros into the buffer. Similarly the delete
commands always delete a unit rather than a character. In a
text mode the delete commands work as in a text editor because a
unit is a character.
Ctl-X I insert-unit
Insert a zero at the cursor position. The rest of the
data moves down one place. Thus, if double words are being
displayed, four bytes are inserted before the cursor position.
These bytes are initialized to zero. This command works in all
display modes.
Ctl-X Ctl-A insert-toggle Insert
In either of the two text modes this command toggles
between insert mode and overwrite mode. In insert mode each
character that is typed is inserted in front of the cursor and
the rest of the buffer is moved down. In overwrite mode the
typed characters replace the character that is at the cursor.
This command has no effect in a non-text display mode.
Ctl-Q insert-literally Esc Q
This command sets a special temporary mode where the next
typed character is inserted in the buffer no matter what the
character is. This allows control codes to be inserted in the
buffer when in a text display mode. Alternatively the same byte
could be inserted into the buffer by using one of the data
display modes. It night be faster to use this command on some
occasions.
18
BEAV User Manual
Ctl-T unit-twiddle
The unit at the cursor is swapped with the previous unit.
Rubout delete-back-char Backspace
This command deletes the character before the cursor and
pulls the rest of the buffer back. The cursor remains on the
same character as it moves back. It only works in the text and
byte display modes.
Ctl-D delete-forw-char Delete
The character at the cursor is deleted and the buffer is
pulled back. The cursor remains at the same position. It only
works in the text and byte display modes.
Esc Rubout delete-back-unit Esc Ctl-K
This command deletes the unit before the cursor and pulls
the rest of the buffer back. The cursor remains on the same
unit as it moves back.
Esc D delete-forw-unit
The unit at the cursor is deleted and the buffer is pulled
back. The cursor remains at the same position.
Esc W copy-mark-to-cursor F7
The area in the buffer from the mark to the current cursor
position is copied into the kill buffer. If the mark is not set
before this command is given an error is reported.
Ctl-W delete-mark-to-cursor F8
The area in the buffer from the mark to the current cursor
position is deleted and placed into the kill buffer. If the
mark is not set before this command is given an error is
reported.
Ctl-Y yank F6
The contents of the kill buffer is inserted into the buffer
at the cursor position. The kill buffer itself is not changed.
3.7 Search and Replace Commands
BEAV has very powerful search and replace commands. The
search and replace string can be entered in any of the display
modes. The search and replace strings can each be up to 256
bytes long. The display mode can be changed at any time while
19
BEAV User Manual
entering the string. Wild cards can be placed down to the bit
level on both the search and replace strings. The wild card
character, '?', will match any value that it is compared with.
When a wild card is placed in the replace string it leaves
the destination data unchanged at that position. Thus, if the
destination contains the ASCII string '41 42 43 44' and the
replace string contains '66 67 ?? 69' the result would be '66 67
43 69'.
Wild cards can be placed in any position that makes sense.
If you want to use wild cards in an ASCII string then you must
switch to another mode to enter them. You can then switch back
to ASCII mode. In this case a '?' will appear in the position
where the wild card has been placed but it appears exactly the
same as a standard question mark. In fact if you type a '?'
over the wild card there will be no apparent change. However,
the character will no longer be a wild card but a standard
question mark. To see the true wild cards you must use a data
display mode. In fact if the wild card has been set on the bit
level then you must go to binary display mode to see its actual
position.
The commands to change the display mode in search and
replace are the same as for the window display mode. The search
and replace strings can be scrolled back an forth and the cursor
moved using the same commands as for the window. While
performing a replace command you can switch between the search
string and replace string by using the 'move-back-page' or 'move-
forw-page' commands.
Esc S search-forw F3
Prompts for a search string then searches from the current
cursor position for the first match. The cursor is positioned
at the first unit of the match.
Esc R search-back
This command is the same as the previous one except that it
searches backward.
Esc T search-again F4
This command repeats the previous search command, forward
or backward. The cursor is first moved one byte in the
appropriate direction before the search is repeated.
Esc % replace F5
Prompt for search string. After entering the search
string hit return and you will be prompted for the replace
string. After entering the replace string hit return. BEAV
will then search for the first match with the search string. If
20
BEAV User Manual
a match is found you will be prompted with '(R)eplace, (S)kip,
(A)ll, (O)ne, (Q)uit'
If you type a 'R' the replace will be done at this location
and the search will continue. If you type a 'S' the replace
will not be done and search will continue. If you type an 'A'
the replace will be done and will be done at all future matches
without pausing for conformation. If you type an 'O' the
replace will be done at this location and the search will stop.
If you type a 'Q' then the search will be terminated.
Ctl-R recall-srch-string
If you enter search or replace previously used strings can
be recalled with this command.
3.8 Exiting BEAV
While using BEAV individual buffers may be saved to disk
during the editing session. When quitting BEAV you must save
all buffers or delete all buffers. There are two commands that
do this.
Ctl-C quit-no-save Sh-F10
If there are any unsaved buffers you will be prompted for
conformation before proceeding. All buffers will be deleted
then you will return to DOS.
Ctl-X Ctl-E quit-save-all Sh-F9
All buffers are saved before exiting to DOS.
3.9 Printing
The data that is being displayed in BEAV can be printed or
sent to a file in the same format as displayed. If the current
window is displaying octal words and a print command is given the
format of the print will be in the format of the window; that is,
octal words.
Esc P print-mark-to-cursor Ctl-Print
To use this command you must set the mark and the cursor to
define the region that you want printed. If the mark is not set
it as assumed to be at the first unit. After you enter the
command you will be prompted with 'Print to:'. You can enter a
file name or a device name to send the print image to. If you
enter 'PRN' most systems will print a hard copy.
This is useful for getting a print out of the current key
bindings. To do this give the 'help' command 'F1'. Go to the
21
BEAV User Manual
bottom of the help window using the 'move-to-end' command 'End',
the mark will be assumed to be at the beginning of the buffer.
Issue the 'print-mark-to-cursor' command. Enter 'PRN' at the
prompt. This should print the complete help buffer and will
reflect any changes that you have made to the key bindings.
3.10 Keyboard Macros
BEAV has the capability of recording key strokes as they
are entered and playing them back later. This is useful for
repeating multi-keystroke operations.
Ctl-X ( macro-start
Start recording key strokes. There is no effect on the
operation of the key strokes. Any previous recorded key strokes
are cleared.
Ctl-X ) macro-end
Stop recording key strokes. The key strokes are available
for play back.
Ctl-X E macro-execute
Play back the recorded key strokes. The key strokes that
were recorded are played back as if they were typed at the
keyboard.
3.11 Key Binding
BEAV provides a user configurable interface. The
interface is controlled by a set of key bindings. This relates
the command that will be executed when a particular key stroke is
entered. There are a set of default key bindings as described
in this manual. These can be changed to reflect your
preferences. When a change is made it is reflected in the help
screen.
Ctl-X ? binding-for-key Sh-F1
This command will tell you what function a certain key
sequence is bound to. When this command is given you will be
prompted for a key stroke or key stroke sequence. BEAV will
report back with the function name.
Esc K bind-to-key
First you will prompted for a function name. Enter the
name of the function that you wish to create a new binding for.
Function names are the names listed in this manual that are of
the form of 'move-forw-unit' or 'display-hex'. After you enter
22
BEAV User Manual
the name hit return. You will be prompted for a key. This can
be in the form of a single standard key such as 'Z'. Standard
key sequences can be entered such as 'Ctl-X Z'
or 'Esc Z'. Special keys can be entered such as 'F1' (function
key 1) or 'Page Down'. It is probably a good idea to not use
keys that are needed for editing. If you bound 'Z' to a
function then you would not be able to enter it as a keystroke
when using ASCII display mode. You could still enter it using
the 'insert-literally' command or doing it in one of the data
display modes but this would be more cumbersome.
Ctl-X L bindings-load
You are prompted for a file name that contains the key
binding that you wish to set. This file is read in and the
appropriate bindings are set. The text in the binding file
should be of the form;
<key name> <function name> <key code>
For example;
Ctl-X Ctl-P move-back-char 0550
F1 move-forw-char 04bb
Ctl-A move-forw-unit 0141
Esc Ctl-T move-back-unit 0354
The easiest way of producing a valid key binding file is to
set the desired bindings in BEAV. Next issue the 'help' command
(ESC ?), then write the buffer out with the file-write command
(Ctl-X Ctl-W). The file created will be a valid format for
loading and can be edited as desired. It is the only reliable
way to get the <key code> number.
3.12 Special Functions
These are the commands that do not logically fit under one
of the previous headings
Gtl-G abort-cmd F10
This command aborts the current command. It can even
abort a partially entered command. Thus, if you have typed an
'Esc' as that start of a command you can type Ctl-G to return to
the normal command entry mode.
Esc A auto-save
BEAV can be set to automatically save the current buffer
after a specified number of buffer editing commands are given.
This command first prompts for the number of operations before
the save is made. If a zero is entered at the prompt, this
23
BEAV User Manual
feature is disabled. The default condition of this command is
disabled.
Esc C compare
This is a powerful feature of BEAV. The contents of two
windows are compared byte for byte from the current cursor
position in each window. There must be exactly two windows to
use this command. These windows can be displaying the same or
different buffers. When a difference is found the cursor in
each window is moved to that position and both windows are moved
accordingly. The display mode does not affect the operation of
this command except in restricting the cursor position to whole
units.
Esc X extended-command
If any command looses its binding, this command allows the
unbound command to be used. A command can loose its binding
because the binding was assigned to another command. When this
command is given you will be prompted for a command name. Enter
the command name that you wish to execute, it will be executed as
if you had typed its key binding.
Esc Ctl-F n-way-combine
The contents of other windows can be copied sequentially
into the current window. This is useful in combining odd-even
proms into an executable image file. To use this command create
an empty window with a buffer file name of an empty or
nonexistent file. Read into additional windows the files that
you want to combine. While in the empty target window, issue
the n-way-combine command. The data in the other windows will
be read into the current window. The next window lower on the
screen will be read first, then the one below that, etc.
For example; if you had two files, promlow.bin and
promhi.bin that you wanted to combine into a file called
prom.bin. First issue the file-visit command (Ctl-X Ctl-V),
enter prom.bin at the prompt. This file should be empty of non-
existent. Next read promlow.bin into a new window with the
file-visit-split command (Esc U), enter promlow.bin at the
prompt. Open another window for promhi.bin with the same
command. Go to the window containing prom.bin (empty). Issue
the n-way-combine command. BEAV will copy the first byte from
the window immediately below the prom.bin window and deposit it
in the destination window buffer as well as advance the dot
position in both windows. It will advance to the next lower
window and copy a byte from there into the destination window and
advance the dot in both windows. This process will continue
until one of the source buffers is exhausted, or the user
terminates the command.
24
BEAV User Manual
The user must take care that the source buffers are in the
correct order. They are read starting at the window immediately
below the current window. If the target window is at the bottom
of the screen then it wraps to the top. In this way any order
can be used and changed at will.
Esc Ctl-S n-way-split
This command is the mirror image of the n-way-combine.
The data in the current window is distributed among the rest of
the window buffers displayed. The current window buffer must be
the only window buffer that contains data. If there are two
other empty window buffers then the data will be divided two
ways. If there are five then the data will be divided five ways
Ctl-L refresh-screen
The screen is reprinted from BEAV's internal buffer. This
is useful if the display is messed up due to transmission errors.
On a PC this is unlikely to happen.
Esc Ctl-V show-version
The version and date of BEAV is displayed in the command
line.
Ctl-X C spawn-shell
A new MSDOS command shell is created. You can return to
BEAV by typing 'exit'.
Ctl-U repeat count
This command prompts for a number to be entered. This
causes the next command given to be repeated by that number of
times. This command cannot have it's binding changed and cannot
be issued using the 'extended-command' function.

6. Release notes
Version 1.20 (3/10/91) of BEAV contains the following fixes
and enhancements;
* Under unix files are created with read/write
permissions.
* Fixed the bug in the terminal I/O routine that caused
BEAV to spin rather than give up control when waiting for a
character.
* Added the ANSI #define that was missing for MSDOS.
* Changed the D16 #define to a unsigned short.
* Called ttclose on error exit.
* Check and limit ncol and nrow to the actual screen
array size.
* Add the ability to load key bindings from a file
automatically under MSDOS and unix.
* Add delete current window command.
* Support VT100 type function keys.
Version 1.30 (7/1/91) of BEAV contains the following fixes
and enhancements;
* Under MSDOS and 16 bit UNIX systems the kill or copy
region could not be over 64K bytes. This limit has been
eliminated.
* The save buffer can be made visible with the Esc Ctl-
W command. The save buffer is not editable.
* All memory allocation errors now pause and ask for
conformation before continuing. In previous releases only
an error message was printed. Since an allocation error
generally means data loss, I have forced the user to
respond. Memory allocation errors are not otherwise fatal
to BEAV, they are probably fatal to the user's data. The
decision is left to the user with the appropriate warning.
* Two commands have been added to aid in working with
PROM files; n-way-split (Esc Ctl-S) and n-way-combine (Esc
Ctl-F).
* The speed of the delete-mark-to-cursor (Ctl-W)
command has been greatly improved.

BEAV User Manual
* All commands that can potentially take a lot of time
can be stopped by pressing Ctl-G.
Version 1.31 (11/2/91) of BEAV contains the following
fixes;
* A serious bug that causes a crash on systems that
trapped the use of dereferenced pointers has been fixed.
* Beav now names the backup file properly under unix.
Previously; if a dot file (.<filename>) was edited, the
backup file was given a garbage name. Now, a backup file
simply has ".bak" appended to the file name.
* You can use the buffers-display (Ctl-X, Ctl-B)
command to; go to, kill, or save a buffer.
* A compile flag for DEC ULTRA was created and a
makeable is included in this release (makefile.utx).
* When a large region was deleted the offset value was
displayed wrong, this is now fixed.
* A bug in the parse_f_name that trashed a variable is
now fixed.
* Regions of never used code have been deleted.
* Under UNIX the file permissions are maintained
correctly when the file is saved.
* A number of un-niceities that lint reported have been
fixed.
Version 1.32 (11/8/91) of BEAV contains the following
enhancements;
* BEAV will now compile and run on the Amiga computer.
