title: Use Join perl function to create variables
body: <p>I am trying to do some thing like this:           </p>
  
  <pre><code>my @Amode=('1','2','3');
  my @Bmode=('1','2','3');
  my @Cmode=('1','2','3');
  my @Atemp=('1','2','3');
  my @Btemp=('1','2','3');
  my @Ctemp=('1','2','3');
  
  my @mode=('A','B','C');
  foreach (@mode) {
      my $newmode = join("",$_,mode);
      my $newtemp = join("",$_,temp);
  }
  </code></pre>
  
  <p>I want to access the @Amode information through $newmode. Is this possible? </p>
