You can create a ruleset parameter in the Project Explorer under a top-level package. You can modify its properties in the Property Sheet and set the initial value of the in and inout parameters in the Execution tab of the Options dialog box.
A local parameter should be seen as a global variable that is scoped to the ruleset. All the ruleset elements have access to it. The other parameters are input
, output
, or
input/output
values. When you want to provide data to the engine, you should provide it as an input
parameter. When the ruleset is executed, the rules should set the output
parameters. After execution, the results are provided in the output
data. If the input
data is modified during the computation, you should set the data as input/output
.
Ruleset parameters can be used with the following elements of a ruleset:
if
clause.if
