(...)lines that are preprocessed, are actually the sequences of tokens, not the raw text of the source. And such sequences can be born in a two different ways - either created directly from the source text, or generated by macroinstruction. Thus we've got a two different "line makers" - one being "source reader" and one "macroinstruction processor".

As we have seen, there is a bunch of special commands, like concatenation operator or LOCAL directive, that may be issued while macroinstruction generates a new lines. In a similar way, there are special commands that are understood and obeyed only by the source reader.(...)
