Agreed. Back in early 90ies, everything was written in MASM and TASM, because C/C++ is just too slow for 1MHz 16bit CPU, with too little memory to facilitate far jumps, required by C/C++.

Those aren't even macros, just the lame C nuisance misnomer.

Name: Anonymous 2014-04-05 17:48

Misnomer? That implies the existence of an earlier use of the word `macro' for programming that C's notion contradicts. But from what I can tell, the earliest origin of the term `macro' comes from assembly macros: for example the [i]705 Autocoder System Macro-Instruction Manual[/i], of which a copy is retained at https://archive.org/details/bitsavers_ibm7053274Instrs1957_6769339 .

Macro-Instructions are easily written commands to the Autocoder which cause it to create sequences of machine instructions to carry out certain commonly used functions. A typical macro-instruction consists of a single line entry writen by the programmer in the same format as a 705 instruction. It will automatically cause the generation of from one to more than a dozen 705 instructions and may also call in desired subroutines of hundreds of instructions.

Browsing through the examples, they seem very similar to C preprocessor macros - a single line is typed, with a few operands, and from what I can determine the Autocoder system fully replaced the line of that macro with other lines, with the operands substituded in at regular intervals. Am I missing something?

If ``only'' Lisp has macros, and Lisp's use of the term ``macro'' isn't even the first, wouldn't it make sense to just use another term for Lisp's macros? That way you don't have to get butthurt when people talk about macros without mentioning Lisp.

Lisp macros are the first real macros. Meanings of words change, so the word macro should only refer to Lisp macros, not to the primitive unhygienic text substitution. Use "text preprocessing" instead of "C macros".

No, that would be stupid. How about we call the things Lisp has ``Lisp macros'' because they are (according to you) so unique, and we'll call everything else just plain ``macros''.

Oh, would you look at that. We already do. So stop whining and bringing up irrelevant concepts.

It's pretty obvious you're just flamebaiting, since you aren't even bothering to not bump.
