Forgotten JP - einar - 2015-09-08
NIRVANA demo code ends like this:
Code:
DO
...
FOR sprite = 0 TO 7
...
NEXT sprite
LOOP
btiles:
asm
incbin "nirvana.btile"
end asmPrevious versions of ZX BASIC compiled it correctly. Latest version 1.4.0s1964 now compiles it incorrectly, as follows:
Code:
__LABEL47:
ld a, 7
ld hl, (_sprite - 1)
cp h
jp c, __LABEL2
__LABEL__btiles:
#line 132
incbin "nirvana.btile"
#line 133It's now forgetting to generate the last JP corresponding to the DO..LOOP statement!
If you would like to compile it yourself, source code is available here:

This is another serious bug based on the optimizer change after version s1935.
Can you download ZXBasic Version 1.4.0s1967 and tell me if it works now, plz? :roll:
