The Copy statement has the following parameters:
|source||The name of the variable, typically an array, which should be copied.|
|target||The name of the variable into which the contents of source should be copied.|
All nodes in the target variable are deleted prior to the copy process. The only difference between Copy and Merge is the deletion of the target nodes.
Erase source, target target(1) = "node 1" target(1,1) = "node 1,1" target(2) = "node 2" target(3,1) = "node 3,1" source(3,2) = "node 3,2" Copy target = source Println Exists(target(3,1)) 'not defined anymore, returns 0 Println Exists(target(3,2)) 'does now exist, returns 1 Println Exists(target(1)) 'not defined and has no subnodes, returns 0
