Of course the timer fires only once, because we undef the timer in its callback. If you want to keep the timer running, you need to move its variable to somewhere that stays alive or never undef it in the callback.

[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?
[jdporter]: I guess that the most direct way of doing it is with some magical incantation involving unpack or whatever
[jdporter]: let me google that for me ;-)
[jdporter]: hex points explicitly to oct, which does the job. :-D
[jdporter]: omg, I f love Perl!
[choroba]: say unpack 'H*', pack 'B*', $mask =~ /0b([01]+)/;
