I'm not sure you want to do what you are asking for. You could do

Update: Arien++ for bringing the error in the line below to my attention. I'd like to claim it was deliberate to prevent the unwary from doing this. It wasn't. It's just something I never do. I'm leaving it as-is with the flag. 

my @array = qw( foo bar baz );
for (@array) {
    eval "$_ = 'value'"; # Error here!!!
}

You now have three vars $foo='value'; $bar='value'; $baz='value';

but unless you know what these names are when you write your script--in which case why bother doing this at all--you have no convenient way of using these vars?

I think what your trying to acheive is an associative array or in Perl's terms, a hash. In which case, to set up a hash from the values of an array, use (for example) 

#name your hash
my %hash; 

#autovivify elements with names from the array..
#using undef simply means they will all be undef.
# (all but the first one would be anyway, this just keeps things consi
+stant).
@hash{@array} = undef;

# then to use your named array elements
# eg. keyboard or web page. Assume we get the string 'foo'
my $varName = getVarNameFromSomeWhere();

# then to use it
$hash{$name} = 'we just gave $hash{foo} this as its value';

#and to print it
print $hash{$varName}, "\n";

I hope I read your question correctly, and this is useful, if not, post a reply explaining a little (lot) more of what it is you are trying to achieve.

Well It's better than the Abottoire, but Yorkshire!
