[COFF] Re: machine code translation,as mental architecture models

It appears that Douglas McIlroy <douglas.mcilroy(a)dartmouth.edu> said: I looked at the manual and I think he's misreading it. The "words" in question are the tokens in the macro definition. The example macros look pretty straightforward, instructions and pseudo-ops that are expanded replacing dummy arguments by actual ones. There's no conditional assembly so each macro is just a parameterized chunk of code. https://bitsavers.org/pdf/dec/pdp1/PDP-1_Macro.pdf R's, John
