Copy

Copies array elements from source to target.

Synopsis

Copy target=source

Arguments

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.

Description

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.

Examples

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
