You might want to use 'hash' for this purpose
my $hash;
my @component = qw / abs def gki jkl mno /;
my $root_dir = 'C:/Stuff/';
foreach my $c (@component){
foreach my $t (qw(this that)){
foreach my $n ('01','02'){
my $csv_file = join '_' => ($c,$t,$n);
$hash->{$c}{$t}{$n} = $root_dir.$csv_file;
}
}
}
Or depend upon your needs, you can simplify the code this way. That way, you will not need to pre-populate the hash.
my $root_dir = 'C:/Stuff/';
my $component = 'abs';
my $this_that = 'this';
my $index = '01';
my $csv_file = (join '_' => ($component,$this_that,$index)). '.csv';
my $csv_file_path = $root_dir.$csv_file;

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
