Perfect! And so simple.
Thanks,

I'd like to shorten-up so redundant code in a switch statement by using a
macro for each case. The following code illustrates the problem. In short,
is there a way to write the PARSE(a,b) macro that will work in the manner
shown below?
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!
