It took me 2 days, but I've managed to make a program in ascii.
|
||
|
|
Using pure characters between 0x20 and 0x7E this program source is made of
|
||
|
|
pure human readable ascii. This is a hello world program, paste to notepad
|
||
|
|
and save with .com extension (the following code contains no line breaks):
|
||
|
|
|
||
|
|
X5))%@IP5YI5Y@5P!%PAP[55!5e 5O!54(P^)7CC)7SZBBXPSRABCABCABCABCABCABCABCABCABCZ[XH+H*hello world!$
