generates a random number between 0 and a system-specific maximum value and assigns it to <gamevar>. Specifically, the maximum values may differ between EDuke32 builds produced with the GCC and MSVC compilers, and/or operating systems. Use of this function is thus discouraged.
displayrandvar <gamevar> <maxvalue_constant>
displayrandvarvar <gamevar> <maxvalue_gamevar>
The displayrandvar commands limit the number to be between 0 and <maxvalue>.
This function must ONLY be used in unsynchronized code. Use in syncronized code is almost certain to cause desyncs.
