pb [Macro]

Purpose

The pb macro prints the definition of a given action, method, or production. It should be used interactively rather than in application code.

Syntax

pb behavior &optional title

Arguments

The behavior argument is a Lisp form which either names a behavior (an action, method, or production), or evaluates to a behavior or behavior name. If it is a symbol, special characters are interpreted as in pc, and package prefixes are optional because the search extends across packages.

The title argument is a string which titles a method.

Value

The return value is nil.

Remarks

If behavior and title are supplied, pb searches for a method of behavior having the specified title. Otherwise, it searches for an action or production named behavior.
