No options

Parameters

TREE = trees

Trees to be extended

NODE = scalars

Node at which to join the tree

JOINTREE = trees

Trees to be joined onto the tree

NEWNODES = variates

New node numbers allocated to each node in JOINTREE in the new tree

Description

BJOIN provides the basic tree utility of joining a tree to the terminal node of a tree. Other tree utilities are described in the description of the TREE directive (which declares and initializes a tree).

The tree to be extended is specified by the TREE parameter, and the NODE parameter indicates the node at which the tree is to be joined. The JOINTREE parameter specifies the tree to be joined onto the tree, and the NEWNODES parameter saves a variate containing the numbers of the nodes of the JOINTREE in the new tree.

Options: none.

Parameters: TREE, NODE, JOINTREE, NEWNODES.
