PURPOSE:To reduce the cost of an electronic computer without increasing its installing space by securing such a constitution where the computer functions to delay the initialization of a program under execution before a main storage is saved and preserved when a system is hung up. CONSTITUTION:A computer 1 has a system hang-up phenomenon and an operator turns on an initialization input key 8. Thus an external trigger signal is supplied to an image save control part 16 and the part 16 immediately gives an image save command to an image save module 5. As a result, a main storage is saved and preserved in an external auxiliary storage device 6. In this case, an initialization control part 18 supplies the image save command as a synchronizing signal and is set under an initialization transmission holding state. While an initialization transmitting command is delivered to an initialization control part 18 from a delay circuit 17 after a fixed time needed for the main storage for its saving. Thus it is possible to easily realize the image saving and initializing jobs without using a complicated relay sequence, etc. |
