Lacing with nodes is somewhat different from lacing with code block. With nodes, the user right clicks on the node and selects the lacing option to perform. With code block, the user has much more control as to how the data is structured. The code block shorthand method uses replication guides to set how several one-dimensional lists should be paired. Numbers in angled brackets “<>” define the hierarchy of the resulting nested list: <1>,<2>,<3>, etc.
