Re: A83: Random values
Thomas:
I ENGLISH...that means you could do something like:
call _random
ld a,94
call _setxxop2
call _fpmult
call _convop1
ex hl,de
ld a,64
call _Setxxop2
call _fpmult
call _convop1
This isn't fast (at all...) but it SHOULD work. You'll now have two random
numbers in HL and DE.
Later,
James.
