I made a "fluent" on the emacs.

  CPL> (make-fluent :name 'fl :value 1)
  #<FLUENT FL [1]>

It seems working well. But.... when I give the command like below

  CPL> (wait-for (< fl 20))

The error message appear as below.

  The variable FL is unbound.
  [Condition of type UNBOUND-VARIABLE]

How can I fix it? Thank you.

While you created a fluent object you didn't bind it to a variable. Try:

(defvar fl (make-fluent :name 'fl :value 1))

Have a look at this tutorial for a more sophisticated example that uses fluents.
