How about something like this:

#define rhc__A 'A'
#define rhc__B 'B'
#define rhc__C 'C'
#define rhc__D 'D'
#define rhc__E 'E'
#define rhc__F 'F'
// etc.

// * not allowed in case statement
#define PARSE(a,b)   case (rhc__##a << 8) | rhc__##b: \
                     status = Parse##a##b();     \
                     break

This depends on a reasonable-sized alphabet, of course!
