Dump3a
New version for the S3a with this new features:
- Dump3a takes advantage of the bigger screen and shows 208
bytes
- Edit mode can now be accessed by the diamond key
- The build in calculator now allows decimal input
- Dump3a has a search function in either hex and ascii mode.
Dump3a is a program for viewing and modifying (CAUTION !!!) any
type of file in either binary and ascii mode. It's provided as an
.opa file.
Installation:
Copy the Dump3a.opa file into any \app directory and install it
as an application from the system screen.
Functions:
The screen is divided into a status line at the top, a dump in
binary mode and a dump in ascii mode. The status line indicates
ths bytes shown and the actual position of the cursor.
<left> moves the cursor one byte left
<right> moves the cursor on byte right
<up> moves the cursor one line (16 bytes) up
<down> moves the cursor one line (16 bytes) down
<page up> moves the cursor one page (208 bytes) up
<page down> moves the cursor one page (208 bytes) down
<psion> o asks for a new filename
<psion> i gives you some information about the file in use
<psion> e or this is a toggle key for editing the current
diamond key file. The Edit Mode is indicted by an arrow at
the left side of either the binary or the ascii
dump.
You can toggle between the binary and the ascii
mode by pressing the <tab> key.
In ascii mode you can enter all characters
available on the Series 3a keyboard and also all
combinations with <ctrl><number> except the
combination <ctrl><009> (this is the <tab> key).
Each character is written directly to the file.
In binary mode you can enter all values in hex-
code (0-9,A-F). The program waits for two valid
keystrokes and then writes the character to the
file. After the first half-byte you can delete
it pressing the <del> key.
Pressing the <esc> key terminates the byte
editing.
<psion> j asks you for an address to jump to.
<psion> c pops up a simple hex-calculator. It works in
RPN-mode. That means that you have to enter
operations like this
number >enter> number operator number ...
Operators can be '+ - * /'.
*** NEW *** Pressing the number sign (#) as the first sign
changes the the input from hexadecimal to
decimal input.
You can calculate only with integers. Dividing
an odd number by an even number gives an
integer.
A nice feature of the calculator is that
pressing <psion>j inside the calculator jumps
directly to the calculated address.
You can edit the number only with the <del> key.
*** NEW *** Pressing the monkey tail (@) deletes the input
line.
Pressing <psion> j or <esc> terminates the
calculator.
<psion> f opens a new screen where you can enter up to 20
characters to search for. These characters can
be entered either in hexadecimal or ascii mode.
In ascii mode you can enter all characters
available on the Series 3a keyboard and also all
combinations with <ctrl><number> except the
combination <ctrl><009> (this is the <tab> key).
Each character is written directly to the file.
In binary mode you can enter all values in hex-
code (0-9,A-F). The program waits for two valid
keystrokes and then writes the character to the
file. After the first half-byte you can delete
it pressing the <del> key.
Pressing the <esc> key terminates the byte
editing.
Pressing <tab> changes between the hexadecimal
and the ascii input.
You can move the cursor with the <right> and the
<left> cursor key and delete characters with the
<del> or the <shift><del> key.
The hexadecimal and ascii lines are updated at
the same time.
Pressing <enter> starts the search at the
current cursor position.
*** NOTE *** The search is case sensitive.
<psion> g repeats the search with the actual search string
from the current cursor position.
<psion> x exits the program.
<menu> let you enter all the above functions.
WARNING:
I will take no responsability for the lost of
any data. I suggest to make a backup-copy of the
files you will modify.
I hope you enjoy the program. Let me know all bugs and suggestions.
