Working with Arrays

Page 89

Using the Un-Link Command

To manually unlink the source and destination array, use the

Un-Link

command. Once the destination array

has been unlinked, it must then be unhidden using the

Un-Hide

command. The

Un-Hide

command is not

available until the destination array has been unlinked.

To manually unlink the source and the destination array, and to unhide the destination array:

Select the source or the destination array in the Array view and right-click.

From the

Array

options menu, select the

Un-Link

option.

The source and destination arrays are now unlinked.

Select the destination array in the

Array View

and right-click.

From the

Array

options menu, select the

Un-Hide

option.

Note:

The destination array must be unhidden in all cases to access the data, regardless of which

method is used to unlink the two arrays.
