64 bit Linux assembly step by step

[Gunther]

Here is the appropriate file for Linux from that thread. The functionality of the program is the same, the files have the same name and there is the same output:

I've uodated the Linux version and fixed a little glitch (stack alignment). So the program will be more robust. The current archive is now UnixU1.zip under the first thread post.

Hi Gunther,
Thanks for nice example  :t
I'm often using it as a reference last time . I hope the series is to be continued
