Global record definition syntax

Global records are persistent structured global variables. The scope of these variables is the entire Knowledge Base; any other variable has a scope limited to the current rule. Global records are addressed by name.

Global record definition example

For example, a global record called UNDER_MAINTENANCE has the following definition:

RECORD
   UNDER_MAINTENANCE DEFINES {
      hosts: LIST_OF STRING ;
   }
END

In a rule, you can refer to one of the slots, as shown in the following example:

$UNDER_MAINTENANCE.hosts

This form can be used in an expression, an assignment, or a primitive. For information about using global records in rules, see Global records in rules.
