Cross Reference Panes

Cross referencing allows you to check whether a register is used in a program, and where it is
used.
The search results indicate output registers in red, input registers in blue.
If the value of a register is different from its set value, it means that the value of the register may
have been overwritten somewhere in the program. In this case, you can search for the registers
using cross references. Check the registers displayed in red, and locate the program that is
overwriting them.
Example
The following cross-reference criteria can be set. The following tables describe the check
boxes.
