in reply to scalar symbolic reference to variables

$name=chr(97);
$$name=1;   # shall set $a to 1
print "$$name\n";
print "$a\n";

results in:

so it DOES work.

But don't use $a and $b, they're used by sort.

perldoc -f sort

Actually, you almost never need symbolic references at all....

    Silly me misinterpreted the output of my testsnippet,
    so fool me for that ;)

    Thanx to all answers especially Joost warning about
    using $a !

    To tell the whole story read this:

    I am working on a cgi producing a two framed set. the
    left frame is showing a dynamically list of links,
    which should be anchored to jump to the letter you
    want by clicking on a link at the right frame.

    so here's what I experimented with:
     for $loop (1 .. $last_id) {
  for $count ( 97 .. 122) {
   $bla=chr($count);
   if ( ($list[1+($loop-1)*2]=~/^$bla/i) and (! $$bla) ) {
    $$bla="<a name=\"$bla\"></a>\n";
    print $$bla;
   }
  }
 }

    I intend to puplish the whole code when it's finished
    an working. It is a database for managing your
    video-cds.
