Do what thou wilt shall be the whole of the Law,

I'd just like to provide my support to anyone that feels the need to fly
into a fit of rage and abuse people who post stupid questions without any
independant thought or research into exactly what they're doing, and most
likely do not even know who or where they are.

Most of you are doing a stand-up job replying to these peoples requests,
but are you going to hold their hands forever?  It's not like there is a
lack of information about this stuff floating about the net.

DoctorOwl

I have been getting rather tired of being asked homework questions.  If there 
is abundant info out there, I refer that person to this info.  This way they 
learn to RTFM.

re just below your '_start:' label:

linux program space, '.text' section, by standard is in read/execute memory, 
so you cannot input to program memory. define a label and reserve some space 
in the '.bss' section which is always writable - but does not contain any 
data at program start, filled w. <nul>-s, by the linux loader. the other 
commonly used section, '.data' can store nay data as well as may be written 
to, but also occupies it's space in the program binary, which .bss does not. 
just for completeness, there is also a '.rodata' setion for read-only data 
- and several others, used by "ld" which are usually of no concern.

.long 0 etc will work, but no other 
data, re '.fill', '.rept' in the manual.

----
	.bss
inputmem:
	.long 0	# as often as required
