> Then why are you multiplying IntuitionBase by nothing? I'm not. Several symbols in C are context dependent, in the same way "=" can mean "is equal to" or assignment in BASIC. "*" is one of these. When used between two quantities (variable or constant), * indicates multiplication as you'd expect. When used in a unary fashion, before a single term, it indicates indirection… a pointer, to be exact. Thus value is a variable, whereas *value is a pointer to the value. The other thing you need to know is that a data type in parens is a "type cast", which explicitly says "change this type to that type". So, if you need to assign a float to an integer, you can say integer=(int)float. So, (struct IntuitionBase *)OpenLibrary(etc) says "cast the quantity which is OpenLibrary(), that is, the result of the call, to type pointer-to-structure-of -type-IntuitionBase". I know, clear as mud, right? It does take some getting used to. Rick
