   Description of dd_stat.mode



   DDSTAT_GOOD:  Normal termination. 

   DDSTAT_IDLE:  Awaiting command.

   DDSTAT_BUSY:  Performing disk processing. 

   DDSTAT_KILLED:  Cases such as forced termination by LeoClearQueue 	(CMD_TERMINATED).  Whether data are restored depends on the 		application. 

   DDSTAT_DEAD:  Abnormal termination.  Restoration not performed. 





   Option macros:



   DEBUG:  Valid only when debugging. 

   START_FROM_CASSETTE:  For cassette startup. 

   NO_USE_RTC:  RTC not used. 

   NEED_DISK:  Do not complete initialization if no disk present (Only with cassette 		startup).
