they really are almost equivalent. I implemented SAL because prefix notation
(log (+ 2 3(* 2 3))) got in the way of musicians learning how to program. You
can use whichever you feel most comfortable with. Sal is sort of like Lua and
uses infix: log( 2 + 3 + 2 * 3)

its called file:
load("v.ins")
file "foo.wav" (srate: 22050, chans: 1)
loop for i to 10
fm-violin(.5 * i, 1, between(55, 880), .1)
end
end

there are both Sal and Scheme examples in Grace's Help menu. note that if you
want to define your own instruments right away that would tip the scale in
favor of learning Scheme right off the bat.

THe working directory is sticky so it should stay wherever you set it. if this
is not happening then its a bug (are you on a mac??)

they weren't abandoned, there just aren't objects in S7. If I had infinite time
Id port stklos or goops to s7 and then i could integrate CM2 and CM3 back
together in one app, which to me would be optimal. after all ,cm2 is actually
written in scheme, not common lisp, so there's no inherent reason both code
bases can be one system.
