The overall summary section gives the overall statistics of the
comparison process. Figure 1 is a representative
example of an overall summary section. Figure 1. Example of the overall summary section

Figure 1 shows the following information
about the comparison:
1
The first word of the title tells you the type of comparison.
The overall summary is provided for BYTE, FILE, LINE, and WORD compare
types.
2
Of the 3 lines in each file, 2 from the new file matched
2 corresponding lines of the old file. These are called matching
lines.
3
There are no reformatted lines.
4
There is 1 inserted line in the new file.
5
The old file contains 1 line that is missing from the new
source file.
6
3 lines from the new file were processed.
7
The old file also has a total of 3 lines.
8
The total number of changes is a summation of items 9 , 10 ,
and 11 . It is a convenient number that
best represents the change activity of the two compared files.
9
The total number of reformats and paired changes. This represents
a sum of items that may be considered to be a single change. That
is, some changes are made in pairs and need only be counted as a single
instance of a change.
10
There were no non-paired inserts. Non-paired inserts are changes
to the new file that have no relationship to the old file
(that is, no deletes from the old file occurred in the same
area).
11
There were no non-paired deletes. Non-paired deletes are changes
to the old file that have no relationship to the new file
(that is, no inserts to the new file occurred in the same area).
12
The listing type is OVSUM. This is the listing type option selected
for the comparison. Other options are: DELTA, CHNG, and LONG.
13
SuperC compared columns 1 through 72. This value provides a convenient
reference for confirming if all the columns in the line have been
compared or only some portion of the line.
14
The longest line length of any line in either file is 80 characters.
