Please do not introduce such macros. I don't really think it's necessary to transform the code to text (it clutters the output), but if you insist on doing it, just do it through a function:
static inline LPCSTR debugscrollcode(INT nScrollCode) { ... }
This is the pattern used throughout listview.c. But in general speaking, if you can do it without macros, then macros are not the answer.
