Using Cross Reference

Use Cross Reference to generate a list of addresses used in your program. Cross Reference
lets you monitor the addresses as you write your program. When you select Cross
Reference, your program is compiled and the Cross Reference table is generated.
The Cross Reference table shows the element name, the network number, and the
instruction. See Figure 5-19. Indirect addresses in the Cross Reference table are shown with
the symbols (*) or (&).
To generate a Cross Reference table, follow these steps:
1. Select View
2. Your program is compiled and the Cross Reference table is generated.
3. You can leave the Cross Reference table up while you are entering your program. If you
change the program and then click into the Cross Reference table, you must update the
table by selecting the Refresh option that appears at the top of the Cross Reference
screen.
4. To view an element in your program, double-click on that element in the Cross
Reference table, and that element is highlighted in the Program Editor.
