Listing output section

The listing output section shows where and what the changes are. Figure 1 is an example of a Listing Output Section for a LINE comparison with a listing type of DELTA.

1

Section title line. It tells you that this is a LINE comparison. Possible compare types are BYTE, FILE, LINE, and WORD.

2

Column header line.

ID: A two-column prefix code that identifies the status of the line. See Listing prefix codes.
SOURCE LINES: The actual text or data from the source files. Under this heading, the actual data from the files is listed.
TYPE: Further breakdown of the ID field. See Type of difference codes for information about TYPE codes.
LEN: The "length" or number of consecutive lines of the selected type.
N-LN#: Indicates the relative record (line) number of this line (or where it is to be inserted) in the new source file. Numbers are in decimal.
O-LN#: Indicates the relative record (line) number of this line (or where it was deleted from) in the old source file. Numbers are in decimal.

3

The scale of the column positions of the input source lines.

4

An inserted (I) line. The RPL in TYPE indicates that it is a replacement line. This replacement involves the line 00001 in both files.

Note: Occasionally, you may see some "unusual" characters on the inserted (I) and deleted (D) lines. These characters represent data that is in a non-character (and therefore not directly printable) format in the input record. Ignore them.

5

An information line that is generated on a comparison listing when a Date Definition process statement is used (see Date definitions) and when the preceding inserted (I) line or deleted (D) line contains a date. The information line shows you the content of the date field as it exists on the input file and the date as used in the comparison. For a full example, see Figure 1.

6

A deleted (D) line.
