>How do I test for the presence of system 7? I dont have access to IM VI.

#ifdef ERRANT_PEDANTRY

You shouldn't test for system 7, you should test for the capability you're
interested in.

#else

/* this ought to work even without fancy system 7 glue or routines */
Boolean Is7(void)
{
  SysEnvRec env;

  SysEnvirons(ENVIRONS_VERSION,&env);
  return(env.systemVersion >= 0x0700);
}

#endif
