missing info on pointers

[jack]

don't see anything on pointers also nothing on type "any"
for example, yesterday I was adding declarations for the gmp library and the gmp_sprintf will take mpf, mpz and mpq types
so I made three aliases to the same function but today tried this

DECLARE function MPF_Sprintf CDECL LIB "gmp.dll" ALIAS "__gmp_sprintf"  (BYREF s AS ASCIIZ, BYREF fmt AS ASCIIZ, BYREF X AS ANY ) as long

and it works for all three types.
hope am not overlooking something.

You are right jack.

I didn't cover much that area in help material. I need to feel this hole.
To be honest I'm still working on the many different ways a parameter can be passed to an external function. Some "ways" a re not 100% covered but I'm working on that in the development background so every new thinBasic version brings improvements on this area even if not mentioned in help.

So, I promise I will work on it.
