If you enter 'X' to select a version to be compared with an external data set, the SCLM Audit and Version Utility - External Compare Panel, shown in Figure 1, is displayed. Information about the selected version is shown in the top section of the panel.

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.

SCLM Group

To compare a version against the member store within SCLM, place a "/" against the SCLM Group and specify the group. This will search for the first occurrence of the selected member in the hierarchy starting at this group.

ISPF Data Set

To compare a version against an ISPF data set place a "/" against the ISPF Data Set and specify the data set name. This will search for the first occurrence of the member in the data set.

Member

If you have chosen to compare a version against an ISPF data set, you can specify the member to be used in the comparison. If this field is left blank, the first occurrence of the selected member in the data set will be used.

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. Choosing SEQ means to ignore differences in standard sequence number columns 72 through 80 for FB LRECL 80 members. Choosing NOSEQ means to treat all columns in the files as data. The COBOL selection means to ignore differences in columns 1 through 8 of the data. Choosing Blank causes SuperC to ignore standard sequence number columns if the data set is FB 80 or VB 255. Otherwise, the comparison processes those 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.
