step-l-system SYSTEMprocedure

Returns a new L-system, created by evaluating each rule in SYSTEM according to the rules defined by define-rule corresponding to the class of the L-system. Any rule that has not been defined by define-rule for the class or super-classes of the system is ignored. When rules are being evaluated, any state is branched according to branch statements in the system (see Manipulating state).
