Using all CPAITAL letters for variable names

I use capital letters for macros only. Is it a good idea
to use all capitals for things like constant variables and variables and
array in global namespace ?

*Some* people also capitalise enum values. I suppose

IMHO, no

but then you shouldn't have many variables in the global namespace...
