Precisely. That's why one convention _IS_ to use uppercase for manifest
constants, and lower case for most everything else:

#define		SIZE		64

char  string[SIZE];

etc. etc. etc. etc.

Granted, they would have very little effect on the comprehensibility of
the printed matter, but in a companion posting I'll show that the rules
are important. As Rahul Dhesi pointed out:

	eNGliSh iS A CASe seNSiTive lANguAgE

This can be read, but I'll bet it doesn't read _QUITE_ as fast as

	English is a case sensitive language.

(Food for thought - coments welcome) Perhaps _THAT'S_ why we capitalise
for emphasis - it creates a tiny "slow down" thus drawing attention to
the text we want to emphasize.
