1) The HS page on prog2 says:

    prog2 evaluates first-form, then
    second-form, and then forms,
    yielding as its only value the primary
    value yielded by first-form.

Is the last word meant to be "second-form"
instead of "first-form" ?

2) Is (prog2 form1 form*) the same as
(progn form1 (prog1 form*)) ?

Yes, I take it you didn't search this newsgroup
before posting.

The code generated by the compiler
may not be the same, but the effect
should be.

Yes; the Syntax and Arguments and Values sections get it right though.

Yes.
