Re: What type are you? Mr Hash, Sir Array, or Miss Scalar?

Doraemon,
There is a way to tell a variable's type by using defined() bla,bla,bla? That is news to me.

I am going to assume you mean some variable seen by your program that comes externally. If it was your own code you would only need to look at the sigil ( % => hash, $ => scalar, @ => array). If that is the case then you could probably get away with using ref (see perldoc -f ref). There are certainly limitations in ref, but I think it will fit your immediate needs.

Cheers - L~R

defined() bla,bla,bla? yeah, right! Just a silly joke. Never seriously thought about that (harhar) But i've tried the ref, and it works just fine...problem solved	[reply]

ref is correct, however you can do it yourself if you want to .. (don't know why you would) you can `my %test = ('test1'=>'value', 'test2'=>'value'); my $hash_ref = \%test; print "hash ref" if($hash_ref =~ m{HASH});` [download] I used that once(before I knew about ref). I don't know if that's horribly bad practice or not, but it works. So basically you could go to the trouble (again I don't know why you would want to) of setting up your own ref via a case statement of regex's Grygonos	[reply] [d/l]
