or even better as

      static const char upmap [] = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";

Don't I just love to quibble!

but seriously: ``let your compiler do the walking''

The original posting also had code of the form
	"ABC...XYZ" [ expr % 26 ]

by introducing upmap, we can now write

	upmap [ expr % (sizeof upmap / sizeof *upmap) ]

which is good for two reasons:
	if we later change the length of the string, nothing breaks
	if we later change the type of upmap, nothing breaks

Change is localized; no additional identifiers are introduced.

PS: The parenthesis are necessary above because multiplicative operators
associate from left to right.  Many people are unhappy with C's operators
because the precedence table is long; do you think think that associativity
is a problem too?
