CROSSREF Manual

COBOL85

Sample Listing

Figure 7-2 shows the first page of the cross-reference listing.

This is the cross-reference file list. It lists the name of each

source file that CROSSREF scanned. In this example, only one

file, COBEX85, was scanned.

Figure 7-2. CROSSREF Listing--File List

The identifier list makes up the rest of the cross-reference

listing. See Figure 7-3. The identifier list describes each

identifier in alphabetic order, showing:

• How it is defined (its attributes)

• Where it is defined (file name and number and line number)

• Where and how it is used in the program

Look at the entry for CAPTURE-CPU-PIN on page two of the

listing. The identifier header indicates that it is the name of

a paragraph that belongs to the section named AA. It is defined

in the file COBEX85 at line 200.

The reference line indicates that the identifier is referenced in

the file COBEX85 at line 150.1 (indicated by code M).

Now look at the entry for the identifier named MEMORY-AS-USUAL

on page two of the listing. The identifier header indicates

that it is part of the group data item SAVE-MESSAGE-STUFF. It

is a level-5 numeric computation item. Its size is 2 bytes,

indicating that it is a 1-word integer. Its offset is 32, which

means that it begins at the thirty-third byte of the record SAVE-

MESSAGE-STUFF.

The reference line indicates that the identifier is referenced in

the file COBEX85 at line 141.
