FIG. 1 is a system block diagram of an embodiment of the present invention. In the figure, it comprises an EWS 1 and a mainframe 2. EWS is basically an automatic login AP11,
JCL / command generation AP12 and terminal emulation A
P13 and monitor AP14.

The automatic login AP 11 responds to the connection request to the mainframe by sending the user environment file 15
While performing the login process by correlating the user name on the EWS side with the user name on the host side while referring to
The command generation AP 12 is activated.

The JCL / command generation AP 12 executes the automatic generation of JCL and commands by the user's operation on the operation screen 16 while referring to the command file 17 (the input operation at this time is input of only parameters). To do.

The terminal emulation AP 13 transmits and executes the JCL and command generated by the JCL / command generation AP 12 to the mainframe 21 in response to the activation by the JCL / command generation AP 12. Also, the terminal emulation AP 13 makes an inquiry about the execution of the transmitted JCL or command and stores the result in the transaction file 19.

The monitor AP 14 acquires the execution status stored in the transaction file 19 and displays it on the monitor screen 20. Also, when an input request is made from the mainframe 2, the input / output screen is opened to perform input / output processing.

The input / output screen 18 is opened for each start job command so that a plurality of job commands can be executed simultaneously.

The mainframe 2 has a JCL / command execution unit 21 and an online (TSS) control system unit 22 for connecting and communicating with the EWS 1.

Then, the line connection is made (step 10
2) If the link fails, error processing (step 10)
3), and if the link is successful, the session is established (step 104). If session establishment fails and connection fails, error processing is performed (step 105), and if session establishment succeeds, login processing is performed (step 106).

If the login is unsuccessful, the login screen is displayed on the operation screen 16 (step 107) and the login process is performed again. For example, if login failure occurs three times in a row, error processing is performed (step 108). If the login is successful, the control process is notified of the completion of the login and the process ends (step 109).

FIG. 3 is a diagram showing an operation flow when the automatic login AP 11 logs out. The mainframe 2 is notified of logout (step 110), the session is released (step 111), the line is released (step 112), the logout completion is notified to the control process, and the process ends (step 113). ).

FIG. 4 shows J of the JCL / command generation AP12.
It is a CL generation operation processing flowchart. A work file is generated in response to the activation by the automatic login AP 11 (step 114), and the JCL is created by the process flow editor 115 (step 115).

The details of the processing flow editor 115 will be described below. J in the JCL template display processing 116
A CL model is displayed on the operation screen 16. The display in this case is displayed as a model of the flowchart. Next JC
In the L component display processing 117, the JCL component is displayed. The display in this case is an icon display. Then, in the next process 118, the process target parts such as files and printers are displayed as icons.

Then, in the JCL creation processing 119, JC
L is newly created and updated. The details of the processing in this case are as follows. In the template calling processing 120, the JCL or the template is called, and the next title / comment input processing 12 is executed.
Create a JCL bedder with 1. Then, in the JCL component gluing process 122, gluing is performed on the model that called the JCL component.

After the template correction process 123, the operation target attachment process 124 attaches the file to be operated to the template. This completes the JCL processing 119.

Next, the JCL created in the grammar check process 125 is checked for grammar, and the JCL registration process 126 is performed.
Then, register the created JCL in a file. Also,
JCL template, JCL created in parts registration processing 127
Create and register templates and parts from JCL deletion processing 12
At 8, the registered deletion is performed.

Then, in the execution process 129, the JCL is transferred to the mainframe 2 and executed. In the end processing 130, the work file is released and all the processing is ended.

FIG. 5 is a processing flow chart showing the command generating operation of the JCL / command generating AP 12. After the work file creation process 131, the process flow editor 132 creates commands. This processing flow editor 132
Will be described below in detail.

In the command component display processing 133, the command component is displayed as an icon, and in the JCL display processing 134, the JCL that can be called from the command is called and displayed as an icon. Next, the operation target display processing 135 displays the operation target of the command.

A command is newly created and modified in the command creation processing 136, but the following processing procedure is performed. A command flow creation process 137 creates a command processing flow, a command component pasting process 138 pastes a command component into the flow, and a JCL pasting process 139 pastes JCL into the flow. Then, the operation target sticking process 140 sticks the operation target.

Next, in the syntax check processing 141, the syntax of the command is checked. The command registration processing 142 and the command deletion processing 143 are possible, and the generated command is transferred / executed to the mainframe 2 in the command execution processing 144. Then, the work file is released, and the process ends (step 145).

FIG. 6 is a flowchart showing the processing of the terminal emulation AP13. In response to the activation of the terminal emulation AP 13 by the EWS 1 (step 146), an initial menu display request is issued to the mainframe 2,
Upon receiving the menu screen by the menu screen transfer process 148 from the main frame 2, the operation screen display process 147 displays the menu screen.

In response to the command input by the JCL / command generation AP 12, the command execution processing 149 inputs a command to the mainframe, and the command is activated on the mainframe side (step 150). On the mainframe side, in response to the activation of this command, the screen is sent to the EWS side by the screen display process 152, and the mainframe screen display process 151 is performed.

Data transfer to the mainframe is performed in response to the data input 153 on the EWS side, and data processing 154 is performed on the mainframe side. The execution result 15
6 is sent to the EWS side and the execution result is displayed 155.

FIG. 8 is a flow chart showing the operation of the monitor AP 14. If there is a status inquiry 167 in response to the activation 166 of the monitor AP 14, an inquiry is made to the mainframe, and a command,
The execution status of JCL and the like, screen information, etc. are sent to the EWS side as mainframe information.

This mainframe information is sent to the status reception process 1
It is received at 69, and it is determined whether or not the screen is the command screen (step 170), and if so, it is determined whether or not to end. If not, the process is passed to the mainframe screen display AP of the terminal emulation AP (step 171). If it is finished, the waiting process is started (step 17).
2).

If it is not the screen of the command in step 170, it is judged whether or not it is the JCL execution status (step 173), and if so, the execution status is output and stored in the JCL execution status file (step 174). ). Then, if it is completed, the waiting process is started (step 175).

If the JCL execution status is not found in step 173, it is determined whether or not the output is from a printer (step 17
6) If yes, output to the printer spooler (step 177). If not, it is determined whether or not it is a warning message (step 178), and if so, a warning screen is displayed (step 179), and otherwise, unnecessary data processing 180 is performed.

The execution status and execution result acquired by the monitor AP 14 can be transferred to the command file 17, and these can be reused for JCL / command creation.

The circled numbers in FIG. 1 indicate the execution order.

[0039]

As described above, according to the present invention, the EW
Since it is possible to control the processing such as automatic login to the mainframe, input of JCL / command, acquisition of execution result, automatic logout, etc. by shell procedure on S, EWS users can operate the mainframe and JCL / command. There is an effect that the mainframe can be used without learning the grammar and so on and without being aware of the mainframe.

Therefore, it becomes possible to realize a back-end processor by the EWS of the mainframe, to eliminate the human interface (interaction of operation with a human), and to construct the computerization only for program execution.

By enabling execution of JCL / commands, acquisition of execution results, and control of processing by the procedure on the EWS, the EWS can be used as a mainframe maintenance processor and automatic maintenance can be performed. .
