The first thing I did was open up notepad, and entered the following test text:
i've created
a text file!
Next, I saved this as file.txt, then went to the command line, typed in 'debug file.txt' and did this:
-d
1794:0100 69 27 76 65 20 63 72 65-61 74 65 64 0D 0A 20 61 i've created.. a
1794:0110 20 74 65 78 74 20 66 69-6C 65 21 0D 0A 00 83 17 text file!.....
1794:0120 00 00 00 00 00 00 00 00-00 00 00 00 00 00 00 00 ................
1794:0130 00 00 00 00 00 00 00 00-00 00 00 00 00 00 00 00 ................
1794:0140 00 00 00 00 00 00 00 00-00 00 00 00 00 00 00 00 ................

Then when I open file with notepad, the contents are:
i've created
a
so then:
I delete all the contents of file.txt, the size reads as 0 KB
Then:
-d
1794:0100 69 27 76 65 20 63 72 65-61 74 65 64 0D 0A 20 61 i've created.. a

0_o ….. hey all that data is still there, and where did that 4 come from?
-rcx
CX 0000
:
So then I do this:
-rcx
CX 0000
:01f
-w
Writing 0001f bytes
-
Then when I open the file in notepad, I get this:
i've created
a ƒxt file!
4 ƒ
so then I tried:
-rcx
CX 001F
:11
-w
Writing 00011 bytes
Which gave me this:
i've created
a
to be continued!…..
