IF Nesting problem and +D Emulation (*solved*)

[boriel]

Code:

while (a band 16)=0 h=a band 5 v=a band 10 if oldh=4 then if h=5 then newx=x+1 elseif h=0 then newx=x-1 end If else if oldh=5 then if h=1 then newx=x+1 elseif h=4 then newx=x-1 end If else if oldh=1 then if h=0 then newx=x+1 elseif h=5 then newx=x-1 end If else if oldh=0 then if h=4 then newx=x+1 elseif h=1 then newx=x-1 end If end If wend

The syntax above is not right. The right one is:

Code:

while (a band 16)=0 h=a band 5 v=a band 10 if oldh=4 then if h=5 then newx=x+1 elseif h=0 then newx=x-1 end If =>> elseif oldh=5 then if h=1 then newx=x+1 elseif h=4 then newx=x-1 end If =>> elseif oldh=1 then if h=0 then newx=x+1 elseif h=5 then newx=x-1 end If =>> elseif oldh=0 then if h=4 then newx=x+1 elseif h=1 then newx=x-1 end If end If wend

I introduce ELSEIF to reduce the IF-nesting complexity. If you use ELSE IF (separately) you'll need an extra END IF at the end for every ELSE IF instance.
Try this and tell me.

And I also noticed that one of my games crahes the Spectrum if ZX Spin is started with enabled +D emulation. Boriel, could you check all your compiler tests with ZX Spin and enabled +D? The game preview of QFJ I sent to you some time ago: If I try to play, the gems cannot be swaped. Without +D Emulation anything works okay.

What does +D do? At this 1st stage the compiler is supposed to be used only in 48K Speccy. I was astounded to hear the BG music in your chess game :!:
