Compare Utility: "Old" and "New" panels

The Compare Utility "Old" and Compare Utility "New" panels are used to specify the "Old" and "New" data sets in the comparison, and the conditions that form the compare subsets. Optionally, you can also specify the name of the copybooks or templates that describe logical views of the data sets and further refine the "Old" and "New" compare sets.

Both panels contain the same fields.

"Old" (or "New") Partitioned, Sequential or VSAM Data Set, or HFS file
You can use this panel to specify the data set, HFS file, WebSphere® MQ queue name, or a CICS® resource to be compared, and to define which records are to be compared. It contains:
Data set/path name
Can be a fully-qualified data set name or a pattern, an HFS file or directory, a WebSphere MQ queue name, or a CICS resource.

For information about specifying a WebSphere MQ queue name, see Specifying an MQ manager or queue.

For information about specifying a CICS resource, see Specifying a CICS resource.

The data set name may include a member name or name pattern in parenthesis. If the member is specified here, the associated Member field must be empty.

When you specify an HFS file or directory, you must enter a full path name. If the path name is longer than the displayed entry field, press the Expand function key (F4) to display a pop-up window in which you can enter a longer name.

Member
If you specified the name of a partitioned data set (PDS) without including a member name or name pattern in parenthesis in the Data set name field, then you can use this field to specify the member name or a member name pattern.
Note: The specification of a "New" member depends on the specification of an "Old" member. If the "Old" member specifies one member, the "New" member must also point to one member. If the "Old" member specifies a member name pattern, the "New" member must use the same pattern or an "*".
Volume
Specify a volume serial number if the data set is not cataloged.
Start key
VSAM only. Works in conjunction with Skip count to specify the first record from the data set to be included in the compare set.

If a start key or slot number is applicable to the data set, records are skipped until a record with a key or slot number greater than or equal to the specified value in the Start key field is found. If the key contains lowercase characters, blanks, or commas, enclose it in quotation marks. Keys can also be in hexadecimal format (for example, X'0102').

Skip count
Works in conjunction with Start key to specify the first record from the data set to be included in the compare set.

The number of records specified in the Skip count field is skipped after the start key or slot number (if applicable) has been honored.

Compare count
This field sets a limit on the number of records in the final compare sets that are included in the comparison.
"Old" (or "New") Copybook or Template
These fields identify either a copybook or a template. If a copybook is specified, it is compiled to create a temporary template that can optionally be saved if edit was requested.
Note: In the case of a copybook, this can be the name of a CA-Panvalet library, or a library accessed using the Library Management System Exit.
Processing Options
The processing options enable you to specify and modify a template that describes the logical view of your data set. The options are:
Copybook/template Usage
1. Above
Enter 1 to invoke data set compare with the specified copybook or template.
2. Previous
Enter 2 to invoke data set compare with the template last used with the specified input data set.
3. None
Enter 3 to invoke data set compare without a template.
4. Create dynamic
Enter 4 to create a dynamic template to be used when comparing.
Edit template
Specify / to edit the template before use. See Creating and editing templates for detailed information about creating and editing templates.
Type (1,2,S)
The type of editing you want to perform.
You can specify one of the following values:
1
Edit the Record Identification Criteria by field first
2
Edit the Record Selection Criteria by field first
S
Edit the source definition for a template using the advanced copybook selection facility.

This option is ignored when editing a dynamic template.

Advanced member selection
Enter "/" to specify a range of members to be selected rather than a specific or generic member name.
Skip member name list
Enter "/" to run without showing the member selection list.
Batch execution
Specify / to generate and edit a batch job to perform the comparison. For more information on editing these statements, see DSM (Data Set Compare).
Note: This option is only available on the "Old" compare panel.
Binary mode
When processing an HFS file, allows you to specify binary mode (selected) or text mode (unselected).
reclen
When processing an HFS file and the Binary mode option is selected, records are derived based on the fixed record length specified. The default is 80.

Can be in the range: 1–32760

Use I/O exit
Allows you to specify a user I/O exit for compressed or encrypted data sets.

This option has two fields. To select the option, enter "/" in the field to the left of Use I/O exit. With this selected, you can then specify which exit to use in the field to the right of the field label.

Note:
  1. The field only displays if Z Data Tools is installed with the option USEIOX=ENABLE, and the Exit enabled field (in the Set System Processing Options panel) is set to YES. If a default is specified with either of those options, it is displayed in the field to the right of Use I/O exit.
  2. I/O exits can only be used to process the data sets that you are using. They cannot be used to process the copybook or template that you are using to format the data set.
