<p>PURPOSE:To inhibit the generation of valid/invalid sound by an application program by setting previously the ihibition for generation of one or both valid and invalid sounds as desired by a user. CONSTITUTION:An application program APL memory control part 1 stores the setting information on the inhibition for generation of the valied/invalid sounds designated by a user for each processing JOB and controls them. When input data given from a keyboard 2 is equivalent to one of JOBs 1-3 and read out, this data is checked by a data checking circuit 11 for I/O part. The valid or invalid sounds is designated by JOB designating circuits 12 and 13. Then the valied and invalid sound generating circuits 14 and 15 inhibits the generation of one or both of valid and invalid sounds. If the input data is not equivalent to any of JOB 1-3, both valid and invalid sounds are produced.</p> |
