    As Brian hinted:
    $x = 0b101; # $x is a number (= 3).
    $x = "0b101"; # $x is not a number, just a string of chars.
    $x = oct("0b101"); # $x is a number (= 3)

    Both Brian and Tassilo have shown you some other ways to go about it.
    Perl is like that - and I regard your approach to the solution as quite
    acceptable.

    Ummm ... I wasn't wearing my glasses, and couldn't see my fingers
    properly. I think '101' is actually binary representation of '5', not
    '3'. Time to visit the optometrist .... or maybe the neurosurgeon.

    thanks

    one more thing,
    what is this " $x is a number (= 3) or (= 5) mean?
    who is (= number) used and what for?

    this is perl, I don't expect an explainatin but maybe a term to google for.

    thanks
