Part of #33. The v6.S listing in the hello_world chapter introduces the PUSH_P, PUSH_R, POP_P and POP_R macros without explicitly telling the reader what the _P and _R suffixes stand for. For a reader reading the chapter in order, the mapping is derivable: the book established stp = "store pair" about 260 lines earlier, and the _R suffix falls out by parallel with str. But a reader who jumped straight to v6.S without reading the stp explanation (as Atcold did in issue #33) has no such anchor and is left guessing. One sentence at the "The push and pop macros simply save typing" paragraph closes the gap: it names the _P / _R suffixes, connects them to the already-taught stp / str convention, and costs a skimmer nothing. The macro names themselves are unchanged; they were already fine for an in-order reader, and renaming would have churned every .S file in the book. |
