is this a GNU program? 
"no docs better than a manual page" or any other kind of description...

honestly, do you expect your readers to analysing your(?) example to be able 
to send the appropriate reply? at least, I myself won't bother with anything 
meaningless like your(?) piece of asm text.
so, please, add some comments which fully explain what it is supposed to do - 
e.g. I won't look for syscall numbers which the linux sources provide by 
their rsp names (the numbers may change!); &c. 

plus, probably, while doing so you yourself might even better understand what 
the concerned program segment does...

the examples which you were asking for are already mentioned or, can be found 
in the links page at http://linuxassembly.org

Amusing! :-)
I wonder if your movie reference got "lost in translation", so to speak.
(given the grammatical state of the initial request)
Guilherme, don't go looking for Luke! Hehe

Use the Source, Luke.  See bc(1)

Make a Calculator! Help-me

I am new in the language assembly and I would like to understand better on the recorders, I am trying to make a calculator that reads two numbers of the keyboard and later addition the two numbers.  Somebody could make this calculator and pass me the source.  So that I can to study.  Thank you!

a 'calculator' is a most simple application of the Forth language. 
examples (Forth compiler/interpreter sources in assembly):
	http://www.lxhp.in-berlin.de/lhpf8.html ('lib4th' ANS-type Forth w. 'nasm')
	http://www.lxhp.in-berlin.de/lhpf4.html ('f4' fig-type Forth w. (G)AS)
