Grab this program, grab the Transactor Magazine (the one with the article
about AmigaDOS disk structure, somewhere near the beginning of '87)
(If you haven't heard of Transactor Magazine, well, you're missing a
great one), and play around.  This is a handy utility for just looking
around to see what AmigaDOS actually DOES with the file when you write
it to the disk.  

The menus in the program tell what all the keys do, so I won't get into
that here.  Actually, it's pretty self-explanatory.  Interpret mode 
(click on the gadget marked 'Interpret') will try and make sense out of
each of the block types, or you can select ASCII or HEX mode.  In ASCII
mode, it will eliminate anything that is not standard ascii characters, 
and in Hex mode it will let you move the cursor around and edit the block.
Note that in Hex mode you cannot see the whole block at once, so you
use the 'Change Offset' gadget to look at the other half.

If you really want the source (there's a couple of GOTO's in it! Gasp!),
send me a disk or something to put it on.  (A disk would be best, I guess)
And something to mail it back in, and make sure I don't have to pay 
anything to do it.

What I had a barrel of fun doing is this:  Use the Find File Header option
on the menu to find the name of a file.  (Make sure you're in Interpret
mode), hit F to go to the first block, and then hit N to see the subsequent
blocks of this file - almost like a real File Editor.  Having troubles on
an adventure game?  Take a quick tour with this program.  You never know
what you'll find (even on your Kickstart disk).

(Hey, you ever run DiskDoctor on your Kickstart 1.0?)

This is Public Domain.  If you want to sell it, well, good luck.

a 'crash indicator'.  If it stops moving, it's crashed, or busy.)
