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)));

[james28909]: but then you have the others as well
[Lady_Aleena]: Renaming things like get_THAC0 to just THAC0 was easy. These are harder.
[james28909]: consolidate the three subs into one
[Lady_Aleena]: Um, what?
[james28909]: check is is data or hash or array and do tasks then return needed data
[Lady_Aleena]: james28909, you might want to look at the other two on my scratchpad.
