No? - Can you give an example of your statement?

(Unless you just wanted to say that in some HLL abstraction like
'printf("Hello world!\n")' there's no [visible] conditional branch.
Likewise in a 'ClearAccumulator' machine instruction, or the like.)

The comparisons and predicates are one key function (not any specific
branch construct, whether on HLL level, assembler level, or with the
(elementary but most powerful) Turing Machine). Comparisons inherently
result in predicates which is what controls program execution).

So your statement asks for some explanation at least.
