variable
A temporary data item in a rule base. The variable is assigned
an initial value that can be modified through rule actions, used as
a rule condition to trigger other actions, and restored to its initial
value for the next round of rules processing. Variables also refer
to shortcuts defined for a larger string that can be inserted in the
body of an answer or inserted inline during a chat session. When the
variable is inserted in the body of the answer or in a chat response,
it is replaced with the value specified in the variable.
