NO NO NO!

	ptr = 0;

and

	ptr = NULL;

are the equivalent.  That does *not* mean that NULL is 0.  NULL is allowed
to be other things -- on one system, it was 0xffff:0x0000.  And char need
not be only 7 bits.

"NUL" is the ASCII name for the octet of all zero bits.  NULL is something
completely different.

(Note that I wouldn't be this pedantic normally, but this is *Terry* saying
this, so I felt kinda obligated ;).)

Sean.
