SCLM Version Compare

If you enter 'C' to select a version to be compared with other member versions, the SCLM Audit and Version Utility - Compare Panel, shown in Figure 1, is displayed. Information about the selected version is shown in the top section of the panel. The bottom section of the panel lists all the matching versions of the member that were included in the initial version selection results. Member versions are considered matching when the Member and Type fields are the same. If the Hierarchy View option was selected on the SCLM Audit and Version Utility - Entry Panel, member versions in different groups appear on this list and can be compared.

The fields for the panel shown in Figure 1 are:

Version: Displays the full name of the selected member version.
Version Date: The date on which the selected member version was written.
Version Time: The time at which the selected member version was written.
Compare Type: Specifies the granularity of the comparison, ranging from entire member to member (File) comparison down to single Byte differences. Line compare is useful for source data. Word compare is most useful for text data.
Listing Type: Specifies the context scope of the listing report. You can get a listing with summary information only (OVSUM), single line differences between files (Delta), differences plus or minus the five unchanged lines before and after changed lines (CHNG), or a listing that includes all of the lines in both files (Long).
Sequence numbers: Specifies whether sequence numbers in the compared files are to be ignored or treated as data. Choose SEQ to ignore differences in standard sequence number columns 72 through 80 for FB LRECL 80 members. Choose NOSEQ to treat all columns in the files as data. Choose COBOL to ignore differences in columns 1 through 8 of the data. Choose Blank to cause SuperC to ignore standard sequence number columns if the data set is FB 80 or VB 255. Otherwise, the comparison processes these columns as data.
Listing DS Name: The data set into which the compare listing is written. You can preallocate this data set, or let ISPF create one for you. If this data set is partitioned, you must specify a member name.

To the left of each version listed is a space for entering the S line command. This command selects the version against which you want to compare the currently selected member version. You can only select one of the listed versions.

Note: More sophisticated comparisons can be done using the ISPF Option 3.13, SuperC Compare Utility.
