Extracting Domain-Based COBOL Components

Select the program you want to slice in the HyperView Objects pane and click the

button. A dialog opens where you can enter the name of the new component in the text field. Click OK. Component Maker adds the new component to the list of components. Double-click the component to edit its properties.

In the Data Item Value field, click the here link. Choose one of the following methods in the pop-up menu:

HyperCode List to set the specialization variable to the constant values in a list of constants.
User Specified Value(s) to set the specialization variable to a value or values you specify.

Select the specialization variable or its declaration in the Source pane. Click the link for the current selection in the Data Item field and choose Set in the drop-down menu. For advanced program specialization, you can enter a structure in Data Item and a field inside the structure in Field.

Note: To delete an entry, select the link for the numeral that identifies it and choose Delete in the pop-up menu. To unset an entry, click it and choose Unset in the pop-up menu. To navigate quickly to a variable or declaration in the source, click it and choose Locate in the pop-up menu.

In the Comparison field, click the link for the current comparison operator and choose:

equals to set the specialization variable to the specified values.
not equals to set the specialization variable to every value but the specified values.

If you chose HyperCode List, select the list of constants in Code Search, then click the link for the current selection in the List Name field and choose Set in the drop-down menu.

Note: Choose Show to display the current list in Code Search. Choose (none) to unset the list. For Code Search usage, see Analyzing Programs in the product documentation set.

If you chose User Specified Value(s), click the here link in the Values field. Choose one of the following methods in the pop-up menu:

Value to set the specialization variable to one or more values. In the Value field, click the link for the current selection. A dialog opens where you can enter a value in the text field. Click OK.
Note: Put double quotation marks around a string constant with blank spaces at the beginning or end.
Value Range to set the specialization variable to a range of values. In the Lower field, click the link for the current selection. A dialog opens where you can enter a value for the lower range end in the text field. Click OK. Follow the same procedure for the Upper field.
Note: For value ranges, the specialization variable must have a numeric data type. Only numeric values are supported.

Repeat this procedure for each value or range of values you want to set and for each variable you want to specialize on. For a given specialization variable, you can specify the methods in any combination. For a given extraction, you can specify simplified and advanced modes in any combination.

Note: To delete a value or range, select the link for the numeral that identifies it and choose Delete in the pop-up menu.

In the Entry Point to use field, click the link for the current selection and choose the entry point you want to use in the pop-up menu. To unset an entry point, click it and choose Unset in the pop-up menu.

In the Description field, click the here link to open a text editor where you can enter a description of the component. The description appears in the box below the Description field in the Properties tab and in the Description property for the logical component repository object.

Click the

button on the tool bar to start extracting the logical component. You are prompted to confirm that you want to continue. Click OK.

The Extraction Options dialog opens. Set options for the extraction and click Finish.

Component Maker performs the extraction. You are notified that the extraction is complete. If the extraction completed without errors or warnings, click OK to continue. If the extraction completed with errors or warnings, click Yes in the notification dialog to view the errors or warnings in the Activity Log. Otherwise, click No.
