Can you mix # and @? It depends on what you're trying to do. The @ is for
GOC and the # is for the C compiler (BCC). If you mix them up the wrong way
then the compilers will get confused and most likely report errors about open
conditionals. Your example looks like it should work okay.
BTW, you don't need the #if ERROR_CHECK when you've got the EC() macro. Use
EC() around single lines that are to be included in only the error-checking
version of your app. Use the #if ERROR_CHECK/#endif around multiple lines
that are to be included in only the error-checking version of your app.
