in reply to Compare two hash values for a match

in your top scope '$name' is never set, i.e. it's undef in all your attempts as hash key.

    Thank you! That made a lot of sense! Since it was not getting defined i couldn't compare my keys to undefined value. I changed it to
    foreach $key(@key2) { $sysdef = $current{$key}{"nodesysoid"}; if (exists $lookup{$sysdef}){ #print "$key, $sysdef, $lookup{$sysdef}{name}, $source\n"; } }

[jdporter]: one prog I have has a UI which allows to input a bit mask
[jdporter]: currently it expects the bitmask to be in the form of a hex number, e.g. 0x0101
[jdporter]: but I'd like to let the user specify it as individual bits, i.e. 0b0000000100000001
[jdporter]: there is no bit/binary equivalent of hex, right?
