Subject: CTRL(x) in the ANSI standard

The suggestion was made to implement a CTRL(x) macro using
an enum:
>	enum _CTRL_kludge {
>		_CTRL_A = 1,	/* upper case control chars */
>		   ...
>		_CTRL_Z,
>	};
>
>	#define	CTRL(arg)	((int) _CTRL_ ## arg)

This won't work for any of the control-chars that are not letters
(e.g. ESC = ctrl-[). Often they are the most useful.

	Somewhere along the line I picked up the habit of saying

# define N	10
 ^ notice the blank after the "#"

	K&R makes some mention about being liberal about surrounding
operators with white space; I guess this is where I got if from (no
flames about # not being an operator, please).  I never even realized
that what I was doing was different from the rest of the world until
someone pointed it out to me (i.e. flamed at me).

	Does this violate the proposed standard?

[ This is legal as long as # is the first character in the source
  file OR the first character after a new line character.  -Mod- ]
