I have never used Ftune, so I cannot provide you with these results.
Here is the fastest 8-queens benchmark version adapted exclusively for CBASIC:

Code:


8➝R : R➝Dim A
0➝S : 0➝X
Lbl 0 : X=R⇒Goto 5
Isz X : R➝A[X]
Lbl 1 : Isz S : X➝Y
Lbl 2 : Dsz Y
A[X]-A[Y]➝T⇒Goto 3
Y=0⇒Goto 0 : Goto 4
Lbl 3 : (X-Y)≠Abs T⇒Goto 2
Lbl 4 : Dsz A[X] : Goto 1
Dsz X : Goto 4
Lbl 5 : S

FX-9860GII-2, integer mode (CBASIC ver.2.45):
t=0.398_sec at 29.5_MHz.
