Remarks
In FFLD language, the input rung (EN) enables the selection. The output rung keeps the same state as the input rung. In IL"Instruction list" This is a low-level language and resembles assembly language, the first parameter (selector) must be loaded in the current result before calling the function. Other inputs are operands of the function, separated by comas.
