INTLIST,[<n1>],[<n2>],[<step>],[<c1>],[<c2>],[<c3>],[<c4>]

lists the set of interaction (if <c1>=1), intermediate (if <c2>=1),interface (if <c3>=1), and internal (if <c4>=1) nodes defined by <n1>, <n2>, and <step>. The default values are: the first node for <n1>, the last node for <n2> and 1 for <step>. If all codes <c1> - <c4> are zero, all interaction, intermediate, interface, and internal nodes are listed.
