CROSSREF Manual

SCREEN COBOL

Sample Listing

Figure 11-2 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, SCOBEX, was

scanned.

Figure 11-2. CROSSREF Listing--File List

The rest of the listing consists of the identifier list. See

Figure 11-3. 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 the identifier named ERR-WINDOW. The

identifier header indicates that it is a level-5 screen field,

which is part of the DRAGON-SCREEN screen. It is defined in the

file SCOBEX at line 92.

The reference line indicates that ERR-WINDOW is referenced in the

file SCOBEX at lines 103 and 188. Both of these references are

read referenced (indicated by code blank).

Now look at the entry for the identifier named INFO1. The

identifier header indicates that it is a level-1 alphanumeric

display item. It is defined at line 42.

The reference line indicates that INFO1 is referenced in the file

SCOBEX at lines 67, 107, 128, 192, 195, 198, 201, 204, 207, and

210. The reference at line 67 is a read reference indicated by

code blank. All other references are write references (indicated

by code W).
