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)));

[marinersk]: But I was looking for a more elegant solution. It appears noone online at this time is aware of one.
[LanX]: go to Nodelet Settings and click "All nodelets off"
[LanX]: SUPER STABLE!!!
[marinersk]: LanX++ LOL Yes, that is another workaround. :-)
[LanX]: strangely you can't disable the XP nodelet
[LanX]: But you can use CSS to hide it
[LanX]: and disoplay the data permanently in your peronal nodelet
[marinersk]: I saw that you could post it on the Personal Nodelet, but you have to provide the content also. No way to auto-populate it. Not that this would solve my distraction problem...
[LanX]: there are template variables to "Auto-populate" it
