Re^2: Symbolic references

[Anonymous Monk]

You've partially lost me with that answer.

What if I may have a variable number of variables..

program.pl var1
program.pl var1/var2
program.pl var1/var2/var3

etc? Is there a programatic way to read N variables into the reference?

I've changed my code to be less terse and hopefully better understandable step by step.

> What if I may have a variable number of variables..

you can put a unlimited anount of elements into '$path' and it will work as long as the intermediate values really exist within the nested hashes (otherwise the result is undef).

??? what do you mean here with "reference"?

I used the wrong word 'reference' it should have been variable. I've tried to impliment your code below, but I'm still lost...

foreach $argnum (0..$#ARGV){
  print "$ARGV[$argnum]\n";              
  my $path=$ARGV[$argnum];
  @path=split /\//,$path;
  $node=node->{$_} for @path;
  print $node;
  }
print "\n";
}

got it! phew!

        
foreach $argnum (0..$#ARGV){
  $node=$ret;
  print "$ARGV[$argnum]\n";
  @path=split /\//,$ARGV[$argnum];
  print Dumper @path; #debugging helps!
  $node=$node->{$_} for @path;
  print $node;
  }
print "\n";
}

Thanks!
