Means.

Next, the operation will be described. First, at the time of creating the user program (1), different signal numbers are assigned to a plurality of termination factors that are considered to occur, and each of those signal numbers and a plurality of termination preliminary processing programs to be executed according to each signal are assigned. End pretreatment means information such as an address is sent to the operating system (2) by the respective ends pretreatment registration information transmitting unit 1, 2 (51) (52), is the information in the operating system (2) Is registered in advance in each user information registration means 1, 2 (61) (62) for each signal number.

Now, it is assumed that two events of termination factors due to different factors have occurred successively, and the operation at that time will be described.
First, when the first event occurs and the end factor event occurrence detecting means (3) of the user program (1) transmits the signal 1,
Operating system generator end cause storage means ends the preliminary processing execution information transmission means (2) (7) (9) receives the signal 1, that kind from this end cause event has occurred and the received signal number 1 Remember. On the other hand, the first signal 1 is also received by the next execution completion preliminary processing determining means (10), and the signal transmitted from the termination factor event occurrence detecting means (3) is stored in the occurrence termination factor storing means (9). Since signal 1 is stored here, it is next determined whether or not the end preliminary processing means information corresponding to this signal 1 has been registered in the user information registration means (6). You.

Since the end preliminary processing means information corresponding to the signal 1 is registered in the user information registration means 1 (61),
The information transmitting means (10) reads the end preliminary processing means information corresponding to the signal 1 from the user information registration means 1 (61), and based on the end preliminary processing means information, the corresponding end preliminary processing means (41). Is transmitted to the user program (1). If the call to the signal 1 in the user program (1), that is, the transmission of the termination preliminary processing means information by the termination preliminary processing registration information transmitting means (5) is not performed, the termination processing means (8) directly terminates the process. Is performed.

Before the end processing of this process is completed, when the next end factor event occurs and the end factor event occurrence detecting means (3) of the user program (1) transmits the signal 2, the occurrence end is terminated in the same manner as described above. The signal 2 is received by the factor storage means (9), and information of the signal 2 is stored therein. However, since this is the second signal, the processing by the next execution end preliminary processing determining means (10) is not performed.

Upon receiving the information corresponding to the signal 1 transmitted from the information transmitting means (10), the terminal pre-processing means (41) of the user program (1) performs the optimal pre-processing for the signal 1 in the pre-processing. When the termination pretreated ends its ends pretreatment completion signal operating system
Sent to (2). Receiving at the operating system (2) in generating end cause memory means the signal (9) and the next execution end preliminary processing determination unit (10), generating end cause storage means (9) of the signal 1 terminates the preliminary processing is completed in The stored information is deleted, and the next execution preparatory processing determining means (10) starts the next preparatory preprocessing operation.

That is, here, the occurrence termination factor storage means is again stored.
It is determined whether the unexecuted signal transmitted from the termination factor event occurrence detection means (3) is stored during (9),
Since the signal 2 is stored here, it is next determined whether or not the end preliminary processing means information corresponding to the signal 2 is registered in the user information registration means (6).
Since the end preliminary processing means information corresponding to the signal 2 is registered in the user information registration means 2 (62),
According to (10), the end preliminary processing means information corresponding to the signal 2 is read from the user information registration means 1 (62), and the corresponding end preliminary processing means (42) is executed based on the end preliminary processing means information. Information is transmitted to the user program (1).

Receiving the information corresponding to the signal 2 transmitted by the information transmitting means (10), the termination preliminary processing means (42) of the user program (1) performs an optimal termination preliminary processing on the signal 2. When the termination pretreated ends its ends pretreatment completion signal operating system
It is sent to the occurrence end factor storage means (9) and the next execution end preliminary processing determination means (10) of (2). The occurrence termination factor storage means (9) deletes the storage information of the signal 2 for which the end preliminary processing has been completed, and the next execution termination preliminary processing determination means (10) again stores the unexecuted signal in the occurrence termination factor storage means (9). Is stored. However, since nothing is stored here, the process proceeds to the end processing means (8), where the end processing of the process is performed.

In the above embodiment, the case where two pieces of end preparatory processing means information are called has been exemplified, but it is needless to say that the number of pieces of information may be three or more.

[0019]

According to the above manner the present invention, according to the present invention, the information of a plurality of respective termination pretreatment means in accordance with the end cause a plurality of Tsu different, pre-operating <br/> computing the call from user program may be registered in the system, depending on the occurrence of end cause event, stores that and its type had its occurrence factor in the operating system, the end of the optimum in accordance with the stored occurrence factor pretreated are sequentially executed in the user program, the ends pretreatment with all the factors have to perform the end processing of the operating system <br/> beam upon completion, it terminates the best know termination factor that occurred Preliminary processing is performed,
