  12. * --------                                                      *
  13. * 8/15/90 KJS        Now plays if it hits either end of          *
  14. *                     stream or a carriage return.                *
  15. *                                                               *
  16. * When debugging, set the project type to application,          *
  17. * and add the ANSI project.                                     *
  18. *                                                               *
  19. * When all your bugs are out, 'undef' DEBUG, set the project    *
  20. * type to Code Resource, with type = ACMD, name = <the name     *
  21. * of the function>, file type to 'AEXT', and the purgeable      *
  22. * flag set to true.                                             *
  23. *                                                               *
  24. * Also, you need to remove the ANSI project from the ACMD       *
  25. * project and replace it with the ANSI-A4 project if you use    *
  26. * any functions in ANSI, such as strlen.                        *
  27. *                                                               *
  28. * If you are not using THINK C, I'm not quite sure what you     *
  29. * should do. :-)                                                *
