Figure 10-2. CROSSREF Listing--File List

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

listing. See Figure 10-3 on the following page. 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 the identifier named PERSONKIND. The

identifier header indicates that is a public variable of type

enumeration. It is defined in the file PASCALEX at line 10

(indicated by code D) and referenced at line 30 (indicated by

code M).

Now look at the second entry for the identifier named

PORTOFENTRY. The identifier header indicates that it is con-

tained in the routine MAKETHEPERSON and is defined in the file

PASCALEX at line 63. The reference line indicates that it is

a parameter of the type PLACENAME and is read referenced in the

file at line 75 (indicated by a blank code).
