The rand function in C returns a random integer. The OP's C code seems to assume 16 bit integers, so that's a max of 65535 (or 32767 to -32768, IIRC). So, I think the equivalent Perl code would be something like:

$gcheck = sprintf "%x", ((int(rand(65536)) << 16) | int(rand(65536)));

[Corion]: hippo: At least for the German translation, the wordplay is translated as well
[Discipulus]: always! but if i can ask choroba why you always use the inverted (to me) form 1 == $.?
[choroba]: To avoid accidental overwriting of the variable in if ($x = 3)
[karlgoethebier]: Corion: Auch in hessisch? Mer wasses net.
[Corion]: Hmm - I'm not sure, I haven't read the mundart/slang translations ;)
[Eily]: $F[1] =~ s/^0//r could be written as (0+$F[1]). It's less explicit though
[Discipulus]: ah! seems wise choroba, you play safe
[shmem]: Eily: also -+-$F[1]
