Tokens & Wildcards In Absorbers
Variable Tokens preceded by “$” or “$_” may be used in Absorbers. System Variables include “$_wild”, “$_wild2”, “$_a”, “$_u”, etc. If a Variable is not present and an Absorber includes that Variable, it cannot be considered; setting a Variable null will thus prevent execution of any Behavior that uses it in Absorber text.
Absorbers can also make use of the “*” (Asterisk character) to populate the Wildcard Variables in the Core. In the below example, suppose you were asking SILVIA about a place in a Map Search context.
With the input “Silvia I am looking for a Museum in Manhattan”, System Variables “$_wild” and “$_wild2” would populate with “Museum” and “Manhattan” in the State Monitor.
