Hi Andreas Strange, I will do some testing this weekend.
Thanks for the update.

As a result the code size increased (+200 byte), but the program doesn't work any more, the output on my display stopped working, so it's hard to further debug this. So it's not clear if this helps or not because then other problems come into. Andreas On Thursday, August 17, 2023 at 10:29:51 PM UTC+2 Rob CJ wrote: Hi Andreas, It might be a optimization issues. Can you add the following to your program and test if the problem is gone? pragma opt expr_reduce no It will disable code optimization. Thanks.

I'm a heavy Jal User I would call myself, but this is the first issue I found over the last years :-) On Thursday, August 17, 2023 at 9:31:13 PM UTC+2 Rob CJ wrote: Hi Andreas, I had a quick look at the generated assemble code for a PIC16. In your first code example the code is (I changed 3 times i into i, j and k so I could compile it): ; 10 i=test1() movlw 0 movwf v_i ; 11 if i>0 & i<13 then movf v_i,w bsf v__bitbucket, 0 ; _btemp1 btfsc v__status, v__z In your last code example where you removed the function the code is: clrf v_k ; 35 if k>0 & k<13 then movf v_k,w bsf v__bitbucket, 6 ; _btemp7 btfsc v__status, v__z If I am right - and I hope I am not - the first piece of code does not work because the Z flag (v__z) of the status register (v__status) is never affected by any of these instructions. In the last code example the clrf instruction sets the Z flag. In other words, moving the return value of 0 to v_i is not the same as clearing the value of v_k. So it might be a compiler bug. I wonder why it has not been discovered before. Still need to see if my draft conclusion is correct.

Can anyone pls verify: var byte i function test() return byte is return 0 end function i=test() if i>0 & i<13 then -- goes here but is wrong else .. end if but this code works: var byte i function test() return byte is return 0 end function i=test() if i<13 & i>0 then .. else -- goes here and OK end if if you remove the function, it works, too: var byte i i=0 if i>0 & i<13 then .. else -- goes here and OK end if -- You received this message because you are subscribed to the Google Groups "jallib" group.
