  30    ------
  31         win32Trace(x)     - Trace macro. Use double in parenthesis for x. Same args as printf.
  32         win32ASSERT(x)    - assert macro, but will not abort program and output sent to trace routine.
  33         win32APICALL(x)  - Use to enclose a Win32 system call that should return TRUE.
  34         win32APICALL_HANDLE(h,api)  - Use to enclose a Win32 system call that should return a handle.
