Subject: Adding to @INC
Message-Id: <BHRCa.6594$JA5.116639@news.xtra.co.nz>
I've just tried running a basic script and it's getting ugly at me, because
it can't find a required package.
Can't locate DBI.pm in @INC (@INC contains: C:\oracle\ora81\Apa
lib/MSWin32-x86 C:\oracle\ora81\Apache\Perl\5.00503\lib C:\orac
erl\site\5.00503\lib/MSWin32-x86 C:\oracle\ora81\Apache\Perl\si
at test_connect.txt line 3.
BEGIN failed--compilation aborted at test_connect.txt line 3.
I'm assuming @INC is the perl equivalent of a PATH.
How do I add locations/directories to @INC so It finds the required package,
and/or where is it described in the docs (I couldn't find it.)
Thanks
Pete

See FAQ (listed in prior post) or, if you prefer/need an object-oriented
context, my List::Compare module, available from CPAN, has method
get_complement() to accomplish this.

Aside from the graph-theory problems, you will also have problems
introduced by your refusal to use strict. Please take care of those first.

Subject: Help: Sort HOH by value?
Message-Id: <90cdce37.0306021609.4ee7f618@posting.google.com>
Hey all
I have a %HoH with $HoH{$key1}{$key2}=$value is there any way to sort
this according to $value? I'm pulling out $key2 as part of a foreach
statement and would like to be sure that $HoH is equal to a specific
$value for the very first key pulled by the foreach...
Thanks!

Yes.
How about letting us know which efforts you made to find out yourself
before you posted here?

There's a library module called "Carp" that has "carp", "croak",
and "confess" functions in it. The Camel book says these are
used to report line numbers in the CALLER of the caller of
carp/etc, rather than in the caller of carp/etc itself.
carp is like warn
croak is like die
confess is like die with a backtrace printed out
"bail" may have been someone else's attempt to extend the
die/warn functionality in similar ways. Or maybe they just
didn't like the name "die". :)
