[fpc-pascal] Parameter with no type defined?

[Graeme Geldenhuys]

Hi,

If I have a declaration as follows... what type is InData and OutData?
Pointers? If it is a generic Pointer type, then why doesn't developers
simply declare it as pointer? What is the advantage of not mentioning
the type then?


procedure TDCP_blowfish.EncryptECB(const InData; var OutData);
begin
...
end
