You can import expressions using the Import CCL function. For details, see Import CCL Command.
Select File > Import > CCL.
Under Import Method, select Append or Replace.
Append imports expressions and overwrites any that currently exist in memory. Expressions that do not match ones being imported are not changed. Replace deletes all expressions in memory before importing.
Select a location from which to import.
Select a file to import.
Click Open.
Important: Take care when importing CCL files because data can be overwritten.
