As it says in the friendly manual...

Quote

Valid characters in labels are letters, numbers, _, $, #, @, ~, ., and ?. The only characters which may be used as the first character of an identifier are letters, . (with special meaning: see section 3.9), _ and ?. An identifier may also be prefixed with a $ to indicate that it is intended to be read as an identifier and not a reserved word; thus, if some other module you are linking with defines a symbol called eax, you can refer to $eax in NASM code to distinguish the symbol from the register. Maximum length of an identifier is 4095 characters.

I couldn't tell ya about dll function names. Ask MicroSoft. I Imagine it's similar...

Best,
