in reply to varying length multi-dimensional hashes

So what you need is an arbitrarily nested hash searcher? Yikes, those can get tricky. See ref, but I'd start out with (pseudo) code like the following:
sub find_value { my $hash_ref = shift; my $level; foreach my $key (keys %$hash_ref) { $level .= "$key\n"; my $value = $hash_ref->{$key}; if (ref($value) eq 'HASH') { $level .= find_value($value); } else { $level .= "\t$value\n"; } } return $level; }
That's untested, and it doesn't do anything that Data::Dumper doesn't do better... but it's a place to start.

    Thanks Chromatic! That looks like the exact answer for traversing the hash. Now all I need is to do is to figure out how to create the hash. My partner suggests using eval. What do you think?

[hippo]: :-D
[Eily]: you mean a dll where the SW was written in perl? That sounds unlikely
[muthusathish]: please help me regarding this
[hippo]: Easier just to go and look at the source, no?
[Eily]: mostly because perl isn't compiled in the usual sense of the meaning, you can't execute the opcodes directly, you need the perl engine
[muthusathish]: i dont have the environment too, but i need to get the logics so that i can re-wite
[Eily]: what makes you think your dll is "perl based" ?
[muthusathish]: i dont have source code too
[muthusathish]: it is used in VB 6 appln, while debugging is getting error
[hippo]: Somebody has. Ask the author.
