CROSSREF Manual

FORTRAN

Sample Listing

Figure 9-2 shows the first page of the cross-reference listing.

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

source file scanned. In this example, only one file, FORTEX, was

scanned.

Figure 9-2. CROSSREF Listing--File List

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

listing. See Figure 9-3 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 COUNT. The identifier

header indicates that it is an INTEGER * 2 VARIABLE (a 1-word,

2-byte integer) stored in blank common.

The identifier is first defined in the file FORTEX at line 5

and again at line 8 (indicated by code D). Then it is write

referenced at lines 11 and 18 (indicated by code W); it is read

referenced at lines 12 and 18 (indicated by code blank); and it

is parameter referenced at line 21 (indicated by code P).
