I thought that a reference in BASIC languages is the same thing as a pointer in C languages. In VB6, ByVal creates a copy of the object (I'm sure it does the same thing in FB), whereas ByRef is a pointer, even to the extent that C APIs that follow the standard calling convention that require pointers will work if you define the pointers as ByRef. Though that same API could be declared ByVal but then you use AddressOf when calling it. [This site][1] seems to reinforce this, at least for VB6. Are things different in FB? Just curious.
