Assembly Language Programs

[Alessandro Coppelli <coppelli_(_at_)_dsea_(_dot_)_unipi_(_dot_)_it>]

Hi to all.
I am interested to developing a little
assembly language programs.

I rode the article written by Thomas Sommers
( http://user.nj.net/~tms/hello.html )
I followed author's instructions but at the end of compilation

  as -o <name>.o <name>.s
  ld -o <name> <name>.o

what I have is

 #./<name>
 #ksh: Operation not permitted


 Someone knows what is happenig ?
