+#X text 22 375 A random walk is a special case of a Markov chain \,
+in which the states are integers and the transitions add or subtract
+a small amount from the previous state to get a new one. Here the "f"
+holds the state. When it gets a bang \, the previous state is added
+to a random number (from 1 to 4) multiplied by a random sign (-1 or
+1). The new value is then coerced into the range from 0 to 100;
