Does random have two arguments or one?  addition, subtraction, etc have
two arguments, whereas assignments only have one.  I think that random
only has one argument also.

In that case I'd prefer

gX = random(<SEED>);

or rand(<SEED>) etc

According to the source code for ogle (vmg/decoder.c, search for
RANDOM), it seems to have only one argument.

That syntax implies two arguments.  Also, 'X ? Y : Z' is C for something
else.  The point of the syntax is to be C like.

Otherwise, good job!  Hmmm, I think I really need to address VM
completeness for the next release.
