Looks like you want to reserve schwartz for where calculating the value to

As far as I know, perl does not free memory (back to the system); you can
never shrink.
You can avoid getting too big in the first place.
You can restart (exec) yourself if you get to big.

Can the () in your data be nested?
If so, you can't use an re. (See: How do I find matching/nesting anything?
in perlfaq 4.) For example,
while (DATA){
print;
print becomes\n;
s/\([^\)]+\)/()/g; # as Bill suggests
print;
print \n;
}
__DATA__
asdf(as(asdf)df)asdf
becomes
asdf(as()df)asdf

You could use two, a function, instead of $two a scalar...
for $one qw(a b c d){
print two();
}
sub two{isn't this a nice $one!\n}
prints...
isn't this a nice a!
isn't this a nice b!
isn't this a nice c!
isn't this a nice d!
But, it's not pretty to embed the function call in a print
When I say, But, it's not pretty to embed the function call in a print
statement, I mean you can't put a function call in a scalar. You can put it
in the list to print.
I haven't tried it, but I think you can put a tied scalar in a scalar and
get the tied behavior, which is what you want.
Try this...
use strict;
my @list = ("a=1","b=2","c=3");
my %hash = map { my @elt = split /=/, $_; $elt[0] = $elt[1]} @list;
for (keys %hash) {
print "\$hash{$_} = $hash{$_}\n";
}
which prints
$hash{a} = 1
$hash{b} = 2
$hash{c} = 3
You have to split a scalar; you cannot split

I think you're saying you want to base your choice on the numeric part of

Yet, you apply the sort function to the whole name!
Note that 'OZ365.log' sorts in front of 'Oz001.log' (because of z vs. Z).

You may want to use sprintf:
