Your errors are most likely coming from trying to give your macro parameters types. The preprocessor literally just copies and replaces for macros. Because of this it's impossible to perform any type checking on its parameters.

Also, if you're trying to make that second line part of the macro, you have to put a backslash at the end of the first line.

Auron is right about the backslash ( \ ) at the end of the line. I made a post b/c i didn't see he said that, then I reread and was like darn...i was beat to it [smile].
