Compare

You can use CA File Master Plus to compare the contents of two data sets or two or more members in a PDS. Use this feature to perform tasks such as identifying or verifying changes made to a data set. Access this utility through the right-click menu, or you can compare data sets and members not listed in your Directory List view by selecting a server and then selecting Compare from the CA File Master Plus, Utilities menu.

Follow these steps:

1. Open the Directory List view.

2. Select from the Directory List view one of the data sets or members that you want to compare.

3. Right-click the data set or member and select Utilities, Compare.
   The Compare Data Set Utility wizard opens.

4. Complete the following fields on the Old Data Set page, or verify that the prefilled information is correct:

   • Data set name
     Specifies the name of the first data set that you want to compare.

   • Member name
     Specifies the name of the member that you want to compare. Perform a wildcard search to select more than one member. Enter an asterisk (*) to compare all members. This field is only active when comparing members in a PDS.

5. Click Next.

6. Specify the name of the data set and member as on the New Data Set page. This identifies data set and member that you want to compare to the Old data set. If you are comparing members in a PDS, the Old and New data sets must both contain the members you want to compare.

7. Click Next.

8. Select the Output Format options that you want to apply.

     • Hexadecimal
       Displays records in three-line hexadecimal format.

     • Single record
       Displays field names and values for each record. If you select this option, you must specify a record layout.

   • Record display
     Specifies which records to display in the compare report. Select one of the following options:

       Displays all records.

     • Mismatched

9. (Optional) Specify a layout for the old and new data sets. Do one of the following in the Old data set layout and the New data set layout groups:

   • Select from the drop-down list a layout displayed in your Layout view.

   • Specify the layout data set and member name.

     Notes:

     • Select Use old data set layout to use the specified layout for both the old and new data sets.
       

     • You must specify a layout for a single record report format. Otherwise, this step is optional.

10. (Optional) Specify selection criteria. Do one of the following:

    • Type selection conditions into the selection criteria text box. For more information on valid selection conditions, see Condition Specifications.

    • Click Layout to build selection conditions based on the contents of the specified layout. For more information on modifying selection criteria, see Modify Layout Selection Conditions. If you specify selection criteria, you can click Validate to verify that the selection criteria listed are legitimate.

    • Click Import to import selection criteria from an existing selection criteria member. This option is only available if you specified a layout with the single record print mode. For more information on importing selection criteria, see Import Selection Criteria.

11. Click Next.

12. Specify the position of the data and length of the compare, if you want to compare only a portion of a data set or member.

13. Click Next.
    A summary page shows the options that you have selected.

14. Click Finish.
    The summary results of your compare are displayed in the Report view.
