Sounds great!

Well, there are a few things you can do.  First, beginer questions are
perfectly welcome here, as long as they are specific to MacPerl, and not
Perl or programming in general.  The Usenet group comp.lang.perl.misc is a
good resource, if not unweildy.  And my upcoming book with Vicki Brown,
_MacPerl: Power and Ease_, should be of use to you as well.  Draft chapters
are available online at the URL in my .sig.

:)  This is not your fault, actually, but the fault of the StandardFile.pl
library, which was written for an older version of MacPerl and is not
completely clean with -w on.  The good news is that this is just a warning,
and aside from the noise is probably not going to mean anything bad.

FYI, the "Diagnostic messages" item under Help should list every help
message that Perl returns.

Looks like you did a pretty good job.  Cheers!

Don't worry, if you stick with it, it _will_ get better.  :)
