Describes operators available on the Consistency tab of the Rule Properties dialog . Also, provides examples of rules that you can create using a particular operator.
In the examples shown in the table, the rule components are displayed in brackets to separate them visually from properties or values. When a string that follows an operator does not start with a bracket, this indicates a single component rule.

---|---|---|
= |
functions as 'equal to' with numeric characters or as 'like' with text strings |
In a filtered subset of 1hp motors: |

IN |
any of the specified values |
