5.9 Using Probability Variables

The ‘prob’ keyword in an assembler program defines a probability variable with a specific name. A jprob or case instruction can contain the name of a probability variable instead of a numeric probability value. There are three supported types of probability variables:

A controlled probability variable can simultaneously be an output probability variable.

An output probabilities array is the means of fetching probabilities learned for case instructions in a choice instruction block by their indices. A location label assigned to the choice instruction block is the name of this array.
