CROSSREF Manual

COBOL 74

Sample Listing

Figure 6-2 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, COBEX, was scanned.

Figure 6-2. CROSSREF Listing--File List

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

listing. See Figure 6-3. 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. 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 COBEX at line 200.

The reference line indicates that the identifier is referenced in

the file COBEX at line 194.

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

The identifier header indicates that it is part of the group data

item SAVE-MESSAGE-STUFF. It is a level-5 numeric computation

item in the Working-Storage section. 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-second position of the record

SAVE-MESSAGE-STUFF.

The reference line indicates that the identifier is referenced in

the file COBEX at line 141.
