Re^3: Symbolic references

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).

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

??? 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"; }` [download]	[reply] [d/l]

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"; }` [download] Thanks!	[reply] [d/l]

Just a minor note: your way to iterate thru different arguments by index is rather cumbersome just do `~$ perl -E 'foreach $arg (@ARGV) { say split /\//,$arg }' 1/2 a/b/c 12 abc` [download] And plz consider using strict and warnings!
