hey i have a problem with a code that i cant figure out what it is
im "fresh meat" in assembly so might be a few things
what i tried to do is
1) open rnd.txt(65kb) file as read/write ( dump.exe it and you get hex numbers on dos)
2) load one 16 bytes list and sort it upwards
3) write the new list ON TOP of the old list
4)repeat 2-4 for the next 4096 lists
5) close the file
thanks for your help!
