Can you tell me EXACTLY what this showing about? I understand about the line you're typing and it'll display in any files... Are this showing the idea of cover somebody else files and fool them thinking it's true...?
Just explain what he was saying in this room about this MS-DOS...

Just a sum of question..
Can you add a line in the file? by typing in MS-DOS...
Ex:
In the txt, it look like this ..
A
C
I want to add a "B" in the between of A and C.. by typing command in MS-DOS..
After that command put, it should be look like this.
A
B
C
...... Of course it will "BREAK" the line and add whatsoever text to put in .. But what about in between the text like this
AC ----------> ABC
