ok, so than what's the diffrence between:
a) movb $test, %al
b) movb test, %al
c) movb (test), %al
c) movb ($test), %al      #if this exists!

and how come when i access kernel ops i use $<oper>

i.e. movl $__NR_write, %eax    #i actually append the address 1?! not 
put the value 1?!

these are very confusing stuff for me. and i would greatly apreciate it 
if explained! thanks a lot Frank!
