Tree Class

Tree objects are instantiated from a session object with the GetTree method.

The following code sample gets a tree, then opens the tree structure associated with that tree:

Local string &TREE_NAME; 
Local string &TREE_DT; 
/* Get and Open the Tree using the Tree API */ 
&MYSESSION = %Session; 
/* Get the Tree Name and Effective Date from the level 0 record */ 
&TREE_DT = "1900-01-01"; 
/* Get and Open the Tree  */ 

/* open the tree with read access only */

&VC_TREE.OPEN("BKINV", "", &TREE_NAME, &TREE_DT, "", False); 
/* Get and Open Tree Structure */ 
&STRUCT = VC_TREE.Structure;
