Secondary lists are created using the s option with the select, sselect or get-list commands. Its is only used when running compare and copy commands.
An example use of a secondary list is as follows:
Create the primary list.
Create the secondary list (using the s option).
Invoke the copy or compare command.
Enter the file name, preceded by a ( (left parenthesis), when the system prompts to:.
The secondary list takes over and is used for output and comparison IDs. When used with the copy command, the secondary list is used to supply the item-ids for the file that you are copying to. When used with the compare command, the secondary list is used to provide the item-ids to compare to.
The end command can be used to deactivate an active or secondary list.
WARNING |
Once a list is active, the next command issued at TCL must be a valid list-processing command, otherwise the list vanishes. For example:
The list generated by the sselect command is no longer active. |
