CA Global SubSystem › Test a Loaded IMOD

Test a Loaded IMOD

Before moving an IMOD into production, you should test it to verify that the IMOD is working properly.

You test a loaded IMOD from the EXECUTE panel of the IMOD editor. From this panel, you can specify argument strings and the initial stack contents. After the execution is complete, you can retrieve the return string and any resulting stack contents.

To test a loaded IMOD

1. Enter X beside the loaded IMOD you want to test.

   The EXECUTE panel appears.

   Note: For information about the IMOD editor EXECUTE panel, see the online help.

2. Review and complete the panel as follows:
   • Complete the SSID and GoalNet Node (if required) fields to identify the CA-GSS address space where the IMOD is to execute. You can execute the IMOD in an address space that is active on the same CPU as your TSO session or an address space that can be reached using GoalNet.
   • Review the following fields to check that the default stack numbers satisfy your requirements. Update the fields as required.

     Work STACK Number

     Redirect SAY Output to STACK

     Redirect TRACE Output to STACK

3. Specify any arguments for the IMOD as follows. All arguments are case-sensitive.
   • To pass a single, short argument string, specify it in the ARG field.
   • To pass multiple argument strings or a long argument, follow these steps:
     1. Leave the ARG field blank, and enter S beside the Specify Alternate Arguments option.

        The EDIT --- ARGUMENTS ISPF editor panel appears.

     2. Specify the arguments.

        The length and content of the individual arguments are governed by the ISPF editor. The aggregate length of all argument strings must be less than 4094, calculated as follows:

        number_arg_characters + number_arg_lines x 2

     3. Press PF3.

        The arguments are retained for the entire IMOD editor session and are passed to any executed IMOD whenever the ARG field is blank.

4. Specify any initial stack contents as follows. Stack records are case‑sensitive.
   1. Enter S beside the Load Initial STACK Values option.

      The EDIT --- INITIAL STACK ISPF editor panel appears.

   2. Specify the stack contents.

      The stack that is passed to the IMOD can contain any records you want. The length and content of the individual stack records are governed by the ISPF editor. The aggregate length of all stack records, calculated as follows, must be less than 32766: number_stack_characters + number_stack_records x 2

   3. Press PF3.

      The stack records are retained for your entire IMOD editor session and are passed to any executed IMOD.

5. Enter S beside the Execute the IMOD option.

   Your request is passed to the specified address space. After an IMOD is executed, the result (as specified by the terminating RETURN or EXIT instruction) and the final stack contents are available for your inspection in the displayed EDIT --- REST RESULTS panel. If an error occurs, an ISPF error indication appears at the upper right of the panel.
