Abstract

According to aspects of the present disclosure, a method for creating a JCL job card comprises obtaining job control language (JCL) function choices and parameters associated with the JCL function choices and transmitting the JCL function choices to a graphical user interface. A selection of a function choice is received from the user, and a customized panel for display is created based on the received function choice selection and the parameters associated with the received function choice selection. The customized panel is transmitted to the graphical user interface, and values for at least a subset of the parameters associated with the received function choice selection are received from the user. The received function choice selection and received values are mapped to an associated JCL command, and a JCL card is created based on the mapping.

First claim

What is claimed is:

1. A method for creating a job control language (JCL) card, the method comprising:
obtaining JCL function choices and parameters associated with the JCL function choices from a storage device of a computer, wherein the JCL function choices are functions associated with an EXEC line of the JCL card;
transmitting for display the JCL function choices to a graphical user interface (GUI) of the computer;
receiving a function choice selection in response to a user interacting with the GUI to specify a job;
customizing, by the computer, a panel for display based on the received function choice selection and the parameters associated with the received function choice selection;
transmitting for display the customized panel to the GUI;
receiving values for at least a subset of the parameters associated with the received function choice selection via the user interacting with the GUI;
mapping, by the computer, the received function choice selection and received values to an associated JCL command, wherein the mapping includes context and syntax required by the JCL command;
creating, by the computer, the JCL card that instructs a mainframe computer to execute the specified job based on the mapping; and
executing the JCL card by the mainframe computer.

2. The method of claim 1 further comprising:
presenting the JCL function choices via a dropdown box generated by the GUI; wherein:
receiving a function choice selection further comprises receiving the function choice selection in response to the user selecting a JCL function choice via the dropdown box.

3. The method of claim 1 , wherein customizing a panel for display further comprises including text boxes for the user to enter the values for the parameters associated with the received function choice selection.

4. The method of claim 1 , wherein customizing a panel for display further comprises generating a notification that a subset of the parameters associated with the received function choice selection are mandatory parameters.

5. The method of claim 1 further comprising:
identifying an expected value type for a select parameter associated with the received function choice selection;
comparing a type of the received value for the select parameter with the expected value type for the select parameter; and
transmitting a prompt to the GUI indicating that the received value is of an incorrect type if the type of the received value does not correspond to the expected value type for the select parameter.

6. The method of claim 1 , wherein mapping the received function choice selection and received parameters to an associated JCL command further comprises mapping the values to the parameters using a keyword-parameter approach.

7. The method of claim 1 , wherein mapping the received function choice selection and received parameters to an associated JCL command further comprises mapping the values to the parameters using a positional-parameter approach.

8. The method of claim 1 , wherein creating a JCL card further comprises:
determining if mapping the received function choice selection and received parameters to an associated JCL command requires more than one line;
determining a destination operating system requires DOS JCL; and
placing a character at space 72 if mapping the received function choice selection and received parameters to an associated JCL command requires more than one line and the destination operating system requires DOS JCL.

9. The method of claim 1 , wherein creating a JCL card further comprises:
determining if mapping the received function choice selection and received parameters to an associated JCL command requires more than one line;
determining a destination operating system requires OS JCL; and
placing a comma at an end of the line if mapping the received function choice selection and received parameters to an associated JCL command requires more than one line and the destination operating system requires OS JCL.

10. The method of claim 1 further comprising:
prompting, via the graphic user interface, the user to select one of: save, submit, and both for the created JCL card;
receiving a response from the user;
writing the JCL card to a file if the response indicates that the JCL card should be saved; and
submitting the JCL card for execution if the response indicates that the JCL card should be submitted.

11. A system comprising:
a hardware processor coupled to memory, wherein the processor is programmed to create a job control language (JCL) card by:
obtaining JCL function choices and parameters associated with the JCL function choices from a storage device of the system, wherein the JCL function choices are functions associated with an EXEC line of the JCL card;
transmitting for display the JCL function choices to a graphical user interface (GUI) of the system;
receiving a function choice selection in response to a user interacting with the GUI to specify a job;
customizing, by the system, a panel for display based on the received function choice selection and the parameters associated with the received function choice selection;
transmitting for display the customized panel to the GUI;
receiving values for at least a subset of the parameters associated with the received function choice selection via the user interacting with the GUI;
mapping, by the system, the received function choice selection and received values to an associated JCL command, wherein the mapping includes context and syntax required by the JCL command; and
creating, by the system, the JCL card that instructs a mainframe computer to execute the specified job based on the mapping, wherein the JCL card is executed by the mainframe computer.

12. The system of claim 11 further comprising:
presenting the JCL function choices via a dropdown box generated via the GUI; wherein:
receiving a function choice selection further comprises receiving a function choice selection in response to the user selecting a JCL function choice via the dropdown box.

13. The system of claim 11 , wherein customizing a panel for display further comprises including text boxes for the user to enter the values for the parameters associated with the received function choice selection.

14. The system of claim 11 , wherein customizing a panel for display further comprises including a notification that a subset of the parameters are mandatory parameters associated with the received function choice selection.

15. The system of claim 11 , wherein the program code further instructs the processor to perform:
identifying an expected value type for a select parameter associated with the received function choice selection;
comparing a type of the received value for the select parameter with the expected value type for the select parameter; and
transmitting a prompt to the GUI indicating that the received value is of an incorrect type if the type of the received value does not correspond to the expected value type for the select parameter.

16. The system of claim 11 , wherein mapping the received function choice selection and received parameters to an associated JCL command further comprises mapping the values to the parameters using a keyword-parameter approach.

17. The system of claim 11 , wherein mapping the received function choice selection and received parameters to an associated JCL command further comprises mapping the values to the parameters using a positional-parameter approach.

18. The system of claim 11 , wherein creating a JCL card further comprises:
determining if mapping the r
