PURPOSE:To ensure a simple confirmation of the program PG executed on that day when the working is started, by reading the storage contents by a comment announcing command out of the comment table TB that stores both the comment and the date of its execution of a processed program PG. CONSTITUTION:Both the comment and the date of its execution are stored previously in the comment table TB14A. With an application of the power supply switch 22 when the working is started, the initial program loading IPL control part 21 starts operation to give a comment announcing command to the address controller CT23 after the end of the IPL process. The controller CT23 reads the date data of the head address of TB14A to the B register RG24 and then puts it into the comparator 26. The circuit 26 compares the contents of the A register RG27 into which the date data of that day is stored from the timepiece circuit 15 and the contents of RG24. When a coincidence is obtained, the coincidence signal is sent to the gates 25a and 25b. Then the data of both the date and comment sent from TB14A are displayed on CRT13 from the display CT28 and via the gates 25a and 25b. |
