I've been fiddling around w/ the rom calls and trying to make a random
# routine, but all it ever spits out is '0' -- what's wrong w/ this?
;store max. value for random # in 'a'
call 4A78h ;_setxxop2 (store 'a' in op2)
call 50B6h ;_random (generate random # in op1)
call 40AAh ;_fpmult (multiply op1 by op2)
call 4EFCh ;_convop1 (store op1 in 'a')
ld (result),a ;store result
