Subject RE: pwd is '/' ???

Ed,
	Thanks for the information -- the [+ +] issue is a minor annoyance, but I can understand
the pure intentions behind it.  When you say chdir was disabled, is it advised, then, to just
use absolute paths for file I/O?  And why does this chdir change not apply to the Execute()
function -- or does it?  

Thanks for your patience -- I'm a pretty solid perl hacker, but Embperl's inner workings are
over my head in most cases.

Thanks,
Philippe

I haven't moved to EmbPerl 2 yet, but I've been keeping an eye on its
issues, as I would like to do so with as little pain as possible.

chdir was removed for performance and cross-platform uniformity.  Note
that chdir did not happen on all platforms in 1.3, so this isn't a
change for everyone.

That is correct.

Apparently, the intention of [+ +] blocks is simple output; there were
some issues that were complicated by having complex statements, so
complex statements were disabled.  If you want to have a complex
statement, put it in a perl subroutine.
