Hi,
I wrote a script, just for fun, to read the environment variables on xp and save them on a text.
here is how i'm reading them, tested on 2 pc's with xp, its working, but is it a valid - safe way?

Code:

org 100h

 mov ds,[es:002ch]
 xor si,si
 cmp byte [si],0
 je done

print:
 cmp word [si],0
 je done
 cmp byte [si],0
 jne @f
 mov al,0dh
 int 29h
 mov al,0ah
 int 29h
 inc si
@@:
 lodsb
 int 29h
 jmp print

done:
 int 20h
