Using and Updating the "SAVED" Status

Using and Updating the "SAVED" Status

When you enter ATTACHED the current visibility status is saved in a backup blanking table. All APPLY operations operate only on the current blanking table, leaving this backup unchanged.

The reason for this is simple: most usage of ATTACHED reveals too much information in the first pass, and it is necessary to go back and repeat the process with some attached categories switched off.


RESTORE SAVED Copies the backup blanking tables to the "current" ones, effectively restoring the initial state.

You can RESTORE_SAVED as many times as you like within a given usage of ATTACHED .

Because the backup tables are always rebuilt from what is currently visible whenever you (re)enter ATTACHED they are effectively "lost" whenever you close this panel. To maintain a backup while performing other operations you can iconise this panel rather than closing it.

SAVE CURRENT Copies the current blanking tables, ie what is currently visible, into the backup ones (overwriting them). This then becomes the new "saved" state.

You can SAVE CURRENT at any time, but doing so loses your original saved state irretrievably.
