LISTARGS _ _ _ _ _ _ _ _ _ _ _ _ switch
If an operator other than those specifically defined for lists is given a single argument that is a list, then the result of this operation will be a list in which that operator is applied to each element of the list. This process can be inhibited globally by turning on the switch listargs.
log {a,b,c}; LOG(A),LOG(B),LOG(C) on listargs; log {a,b,c}; LOG(A,B,C)
It is possible to inhibit such distribution for a specific operato r by using the declaration listargp. In addition, if an operator has more than one argument, no such distribution occurs, so listargs has no effect.
