Hmm, I fear, this again is *not* re-entrance. As far as I know, this
term only deals with the same piece of code used by more than one
task, like in a shared Amiga library. If you just launch an Amiga
program twice, its code is twice in RAM (as long as this code is not
concentrated in a library), so I don't think this has anything to do
with re-entrancy.

(Grr, can't crosspost to the Mac Newsgroup...)
