Detailed Description

Utility node used to "hold" nodes in a graph that might possibly not be reachable by other means or which should be reachable immediately without searching through the graph.

Each firm-graph contains exactly one anchor node whose address is always known. All other well-known graph-nodes like Start, End, NoMem, ... are found by looking at the respective Anchor operand.
