Implement Changes

This section provides scenarios for customizing the knowledge base with the following actions:

• Disabling an existing rule
• Modifying an existing rule
• Adding a new rule
• Changing a threshold value
• Changing a rule literal value

While the scenarios assume that your auxiliary rules file is called MYRULES.VPR, you can name it whatever you like, provided that it conforms to standard OpenVMS naming conventions.

There are two files to which you probably need to refer when making changes to the factory rules. The first is a copy of the source file for the factory rules, located in PSPA$EXAMPLES:PSPA$KB.VPR. The second is the message text file (which contains the Conclusions and Evidence headings), located in SYS$SYSTEM:PSPA$MSG.TXT. You should make a copy of each in your private directory to modify; do not edit these files directly.
