************************************************************
The Disk Sector Editor (DSE) is a utility program that permits you
edit sectors on a 360K floppy diskette, by sector number or, on a
filename basis. You can edit in ASCII text mode or hex value mode
if you know what you're doing.
Here is a list of function keys, what they do and other operational
information. These instructions are inside DSE as well:
F1-Select a floppy disk drive. Reads in the first data
sector. If ON, it will turn off Edit and File Modes.
F2-Select an absolute sector to read. This is the non-
file mode. Max window displays the last sector number.
F3-Find text string. Works in sector mode or file mode.
In file mode, search is within the file sectors only.
F4-File ON/OFF. File ON means tracing through a file
sector by sector vs absolute sectors. File mode is ON
when a file name is in the upper right File window.
F5-Toggles between low ascii characters and high ascii
characters for the ASCII display. Low characters are
from 0-127 and high characters are from 128-255.
F6-Toggles Edit ON and OFF. Allows editing of sector
characters in hex or ascii. F3 will toggle between the
hex and ascii side for editing. Edit ON can be used
with File ON if you want to edit/page through a file.
F7-Automatically moves through sectors forwards or back-
wards. Automatically shuts off at sector limits.
If ON, it will shut-off Edit and File Modes.
F8-Displays all the data contained in the Boot Record.
F9-General Help information.
F10-Press F10 or ESC to quit the DSE program.
Top part of the DSE screen:
Drive: Currently logged drive.
Drives: Drive range. You have drives installed
ranging from A to D, A to G, etc.
Current Sector: Current absolute sector being displayed.
Sector Size: Sector size in bytes.
Max: Maximum number of sectors on this drive.
DATA: Sector location: BOOT FAT DIR DATA
Tells you what part of the sector is
currently being displayed.
File: When File ON, file name displayed here.
Cluster: Current cluster number displayed here.
DSE can be copied onto your hardisk. However, for safety
reasons, DSE operates only on 40 track, 9 sector, double
sided floppy diskettes. This forces you to do your file
editing on a 360K floppy and not on your hard disk.
You may start DSE with a command line tail. For example,
typing DSE B <CR> will start it from a hardisk and cause
DSE to look at drive B for a diskette. If you just type
DSE <CR>, DSE will look at the default drive and if it's
not what it expects, DSE will prompt you for a drive.
The Escape (ESC) key can be used to back out of, or
"escape" from, almost any area you get into.
Don't use DSE on Master Diskettes. Make a copy of the
diskette you want to modify. Use DSE on this copy. Make
the desired changes. Test the file to make sure it
operates properly. Once you are satisified, copy the file
to it's working diskette or hard disk.
USE DSE WITH CAUTION. EDIT OPERATIONS ON THE FAT TABLES SHOULD
BE LEFT TO ADVANCED USERS ONLY. YOU CANNOT EDIT THE BOOT RECORD
FOR SAFETY REASONS.
DISCLAIMER
You are encouraged to make copies of DSE for others to evaluate, for
distribution on Bulletin Board Systems (BBS's) and computer clubs, etc.
You may not accept payment for doing so however.
You are completely responsible for determining the fitness or usability
of DSE. I will not be liable for any damages, of any kind, arising from
any failure of DSE to perform as expected. There is no warranty of any
kind. By using DSE, you agree to this.
Thank you for using the Disk Sector Editor
