а savebin происходит только во время pass 3 ?

Yes, it's saving bytes from DEVICE memory, which is not used in first passes during assembling, so it's completely zeroed in pass 1/2, and there's nothing to save.

The machine code production happens in third pass (also for OUTPUT/OUTEND/SAVETAP/... all the others).
(production = writing it... the machine code is "dry-simulated" in first 2 passes, ie. the assembler calculates how many bytes the instruction takes, to adjust labels, but then it throws away the opcode)

So in recent weeks I was abusing sjasmplus script a lot (as a form of test/exercise of the scripting implementation, some of the experience went into improving it just before v1.18.0 release)...

If you are serious about sjasmplus scripting, maybe you can pick up a trick or two from these:

почему не работает != ? o_O
почему =! дает какой то результат?

[Ped7g]

почему не работает != ? o_O

Looks all correct to me?

The first part is doing "skip" when cnt is 0 or 5 or 7 or 8

The second part is doing "ok" every time (first two "(cnt is not 0) or (cnt is not 5)" are enough to be always true for any cnt value)

The third part "=!" is parsed as: "=" is equivalence operator, "!" is logical not, so 0 becomes -1, and non-zero values become 0
That leads to "ok" when cnt is -1 or 0

Fourth is just syntax error, the "<>" operator doesn't exist in sjasmplus.

Did you want in second block negation of first block? Then: !(A || B) = (!A) && (!B)
(note the "logical or" becomes "logical and" when whole expression is negated)

tmp_cnt = 0
	dup 10
		if ((tmp_cnt != 0) && (tmp_cnt != 5) && (tmp_cnt != 7) && (tmp_cnt != 8))
			display tmp_cnt," ok"
		else		
			display tmp_cnt," skip"
		endif
tmp_cnt = tmp_cnt +1

значит у меня не правильное понимание || и(людское) &&
и значит (|| людское and &&) != ((людское OR) людское and (людское AND))

[Ped7g]

logical or (T = true [-1 in sj], F = false [0 in sj]):
F || F = F
T || F = T
F || T = T
T || T = T

logical and:
F && F = F
T && F = F
F && T = F
T && T = T

logical not:
!F = T
!T = F

And the general math rules for propagating logical not in complex expressions:
!(A < B) <=> A >= B
!(A == B) <=> A != B
!(A || B) <=> !A && !B
!(A && B) <=> !A || !B
...
https://en.wikipedia.org/wiki/Negation#Distributivity

sjamplus treats any non-zero value as true, and zero value as false, but when boolean-true is calculated, it is represented by ~0 (-1).
value = 4 ; value = 4
value = !4 ; value = 0
value = !!4 ; value = -1 (true)

( "людское ponimanje" => no idea what you are talking about, the math way is the only way I think about logic, even when talking in human language ... but there are many people not able to correctly negate predicate ... for example they ask you if you like blue colour, and you say "no", they will think you hate blue (which is incorrect negation "!like" is not "hate"))

не знаю как у вас
у нас когда люди говорят

если (if)
A не равно 1
или (or)
A не равно 5
тогда (then)
Ы = 7
если нет (else)
тогда Ы = 0


это имеется в виду (и это правильно)

if A <> 1
  if A <> 5
  Ы = 7
  else
  Ы = 0
  endif
else
Ы = 0  
endif

и ожидаемый результат
1 Ы=0
2 Ы=7
3 Ы=7
4 Ы=7
5 Ы=0

такое никогда не имеют в виду

if A <> 1
temp1 = 1
else
temp1 = 0
endif

if A <> 5
temp2 = 1
else
temp2 = 0
endif

if temp1 = 1
  Ы = 7
  else
  if temp2 = 1
  Ы = 7
  else
  Ы = 0
  endif
endif

и такой рeзультат
1 temp1=0 or temp2=1 = Ы=7
2 temp1=1 or temp2=1 = Ы=7
3 temp1=1 or temp2=1 = Ы=7
4 temp1=1 or temp2=1 = Ы=7
5 temp1=1 or temp2=0 = Ы=7
совершенно неожиданный



людскими словами описывается совершенно другой процесс
а такой вариант правильный только с точки зрения машинной логики
и людскими словами описать его намного сложней (это будет достаточно много слов)


к вам претензий нет
просто это не совсем очевидный аспект

пофиксил

поэтому и нужон долбанный список условий по типу if a=1,5,6
а не трехэтажные IF-ы
в которых можно чего то просмотреть

или нужны элементарные for и goto
чтоб не городить огород из dup-ов и if-ов

додо знаю щас ТЫ начнешь мне расказывать что
компилятор не должен это делать
это должен делать cpp, линкер, хренкер прочая ересь
и весь исходник должен состоят из батников
а компилятор должен только заменять nop на $00 и ничего более
и даже не должен делать переходы на метки вперед
и все метки для переходов должны быть предварительно объявлены в начале исходника
а то ж ведь компилятор еще не знает куда ему переходить когда код выглядит так

yeah, we say "if not equal to 1 and not equal to 5". I guess some people could use "or" there, but they are just using the language wrong, or not understanding the logic expressions. (mind you, while I didn't finish my university studies, I made it far enough to have all exams from math basics, like logic evaluation, so for me it's easy to use the language correctly in logic constructs ... but from my experience with people who didn't study it, it's common they don't understand the rules correctly, and say the wrong thing, while they think something else - very common by non-math people, it's not easy to formulate the rule correctly in human language, even by intelligent people, if they are missing the formal math teaching).

But I think your example is actually correct if read in certain way, like this: "if A not equal to (1 or 5), then B = 7, else B = 0" -> now this makes some sense also from math point of view, a bit like incomplete distribution of negation, so you end with something like "IF A != (1 || 5)", but if you expand it to simpler statements, it needs the || negation, so "IF A != 1 && A != 5"

Any way, you can in sjasmplus source always try to pick the "simpler to read", so if you are more familiar with "1 or 5", then do the positive form and negate the final result, like this:

  IF !(A == 1 || A == 5 || A == 7)
    ;; other values of A (not 1 or 5 or 7)
  ELSE
    ;; when A is 1 or 5 or 7
  ENDIF
  ;; notice the "!" at beginning of the expression
  ;; flipping the final result of the test
