Folks,
# How do I sort an array by one of it's fields?
I have a this code:
for ($i=1; $i<=$N; $i++) { }
$dummy[$i][0] = &ParseDate($data{$key}[$i][0]);
if (! $dummy[$i][0]) { }
warn "Could not parse $data{$key}[$i][0]\n";
}
$dummy[$i][1] = $da
Thnaks a lot Jos. The idea of reading the array into a hash is quite appealing, and
simple too. But I have a small problem with this:
What if I want to sort on the second column of the array? Or if there are more
than two columns?
Say we have:
my @arr = qw(
1 2 3 4
4 5 6 7
5 6 7 8
1 2 3 4
3
Thanks a million to Jos Boumans, and Me (whoever that is). Me, thanks for
the explanation, and Jos, for your patient and detailed answer.

Folks, how do I load extra modules? I got Date::Manip today, and I know I
should be putting it in the search-path of perl (@INC ?), but how do I do
it? Can I get a small code snippet?
I do not have su privileges on the machine I work, and would like the
search-path to have my modules dir, $HOM

Brett was right. I tried installing it, but wasn't successful. I then got
the Sys Admin folks to install it, and it went just fine!!
Apparently
Folks, I have a file like this:

Many thanks to Paul. His solution works.

What is the simplest way to read in a matrix, say
19911231 12200 4274
19921231 12205 7822
19931231 3313 8208
19941231 2362 12292
19951231 4348 11673
19961231 11751 14255
19971231 6318 12339
19981231 14901 11530
19991231 373 17353
in perl? I just know that the matrix has to have three
