Hi,
Can someone tell me how to convert an array to hash.
Each array entry has a row of values
e.g. a(0) = ab cd ef; a(1) = mn de fg
The hash array needs to be constructed with one of the element in the
array row as the key.
e.g. hash{ab} = cd ef - ab is a string in the array row

I got an array of values where the order is relevent, eg the ages of
Alice, Bob and Charles, and I want to make a hash out of it. I got
this code that does it:
my %ages = (alice => $r[0], bob => $r[1], charles => $r[2]);
Is there a more elegent way to do it?

Hi All,
I want to read contents of a dir, filtered, into a hash. I have this:

use strict;
my (@ARRAY, %TEST, $FILTER) = "";
print "Enter filter:";
$FILTER = ;

This gets just the info I want,

you could of course generate the file in the form

Drieu :
Whoops. I forgot the chomp. The data in the LABEL_FILE is formatted as:
"key"=>"val", "key1"=>"val1", which seems to work since the for loop
prints as expected.

Below is part of some code that reads from a file to an array and then
