I would stick with this version. The argument to -b is a bundle
identifier, so if Help Viewer ever moves your code will continue to
work.

I see no mention of -b in 'man open' on 10.3 or earlier. Is it
undocumented, or is it only in 10.4?

Apparently it is new in 10.4....

   open [-b bundle_identifier] file ...

....

   -b bundle_indentifier
   specifies the bundle identifier for the application to use when open-
   ing the file

I've been using Tiger long enough that Panther is becoming a distant memory. :-)

If -b is 10.4-only, then it might be safer to use the "help:" URL scheme,
or the ".help" file suffix.

Or better yet, make the whole thing a pattern-based property:
app.help = open!$

Then break it apart at the !'s, substitute $ with the URL of interest, and
exec() the resulting String[]. A nice side effect is that you can change
the property's value on Windows, and the code remains the same.

Sure looks like it would work. If supporting Panther or other platforms is important, this may be your best bet.
