This Program Has An Update Function Which Allows The User To Store Data To

Data On The Disk.

I Cannot Be Responsible For Any Lose Of Data.


                           Sector Editor (Why ?)

The Story.

 I Had A Friend Who Had Some Nasty Words In A Program. I Told Him To Load
 The Program Into Memory, Alter It And Save It Back.
 Then A Few Days Later I Needed To Change A BootBlock I Wrote.
 So I Wrote A Program That Loaded The BootBlock In Created A Checksum And
 Saved It Back. All Editing Was Done Using A Monitor Program.

 So I Decided To Write A Program That Loads In Any Sector
 Creates Checksums,Formats Disk (Allowing You To Store Your Favorite
 Boot Block On It) Loads and Save Parts On The Disk To A File
 And Best Of All Edit In Hex Or Ascii

 LOAD

This Command Loads A File From A Disk/Ram And Stores It Onto The
Disk.

  E.g.
  Start = 0
  End   = 1
  File  = RAM:BootBlock

The Above Would Load In The RAM:BootBlock File And Store It To Disk
On Blocks 0 And 1
If The File Is Shorter Than 2 Blocks Then Only The First Few Lot Of
Data Is Saved

See Warning Message At The Top Of This File

   -5-


 SAVE

This Command Saves The Blocks From The Disk To The Disk/Ram

E.g.
    Start = 0
    End   = 1
    File  = RAM:BootBlock

The Above Would Create A File Called RAM:BootBlock Which
Contains The Data On Blocks 0 and 1.

Storing This In S: Dir Under The Name Of BOOTBLOCK Will
Automaticly Write This Boot Block On The Next Format. When
The Program ReRuns

   -6-

 CREATE CHECKSUM

This Command Creates A Checksum On The Current Block In The
Editor Window. However It You Are Creating A Checksum On The
Boot Block It Will Load The Boot Block From Disk Then Rewrite
It Back To Disk. It Does Not Update The Editor Window And Does
Not Store The Current Editor Window To Disk Before Calculating

On Other Blocks Not The Boot Block It Will Calculate The Checksum
And Update The Editor Window.

 CLEAR BLOCK

This Command Clears The Editor Window And Sets All The Bytes To
$E5 As If You Were Editing A Formated Block

 FORMAT DISK

This Command Formats A Disk. It Is Very Powerful I Managed To 
Format Some Old PC Disks. That Would Not Format With My Normal
Disk Formater.

It Also Has A Built In Boot Block Which I Found Useful But If 
You Dont Like It Just Store The Boot Block You Do Want In The
S: Dir Under The Name Of BOOTBLOCK Before Running The Program

To Enter The Disk Name. Click On The Box,Delete The Old Name And
Enter The New One. Click On O.K. The Screen Will Turn Red Then It 
Will Start Formatting

Note: Do Not Change My BootBlock It Belongs To Me.
