@Donald,

thank you for your advise.
Seems, I have something learned today.

Nevertheless I'm still the opinion, that it was more error proven, if I always see any non zero expression as true, independent, if it was returned by a compiler function or by a self written function.

Furthermore it is always more fault avoiding, if every variable was not assumed that it can hold only 0 or 1.

Thus I wrote my programs always in this way, that any value of a variable cause always a meaningful next state and never a hanging state by receiving an unexpected value.

Also I decide strictly between logical and arithmetic expressions and thus I have no problems to see, when I must use &,| and when &&,||.

Thus writing:

z = (a > b) ? 1 : 0;

looks better readable for me, the assembler output should be the same.
