why not 'ns'? is there any other program with this name?

i dont think nstest can be good for anything. the ns code can be in a
external file test.ns and then you can run it via 'ns'

$ ns < t/test.ns

unless you want to show how to bind C functions to 'nscript', i would
prefer not to have 'nstest' program.

good! but i think that it will be better to have a single way to define
strings. it makes the parser simpler and the syntax more consistent.
which char do you prefer? because if you can escape chars i think '"' is
better than '''. In the other side. I see ''' more to enclose chars than
strings. Is there a way to get the ascii code of a string? or to get the
Nth char of a string? it will be good to have some lisp functions on it.
functional programming is fun(ctional) :)

I will test it again tonight and give you some more hints :)
