It's not surprising that the examples in the docs are correct if you
are working in the Mac Classic environment, since, to my knowledge,
RunRev (or at least Jeanne DeVoto, who wrote the first version of the
docs) was working primarily in the Mac OS classic environment at the
time the docs were first written.
I'll admit, this threw me for a loop when I first switched over to OS
X. I couldn't for the life of me figure out why my file paths didn't
work, until I figured out the Unix/OS X convention of "/" referring to
the boot volume.
For an introduction to file paths, written for beginning Rev coders, see
I've tried here to distill my sometimes painfully-acquired knowledge
to help my students avoid the pitfalls I encountered as a noobie. As
always, if anyone comes across inaccuracies, I'd love to get feedback.
