RECALL allows you to recall previously deleted entities 
and display them on the screen, if appropriate.

Choose a recall method using a Masking Menu option.

Mask on the entities for recall by choosing from the
following options:

LAST - to recall the last entity deleted and display it on
the screen. You can recall up to 100 deleted entities.

LEVEL - to recall the last level deleted and display it on
the screen. Enter the level number (1-256) from which to
retrieve entities and press <Enter>. If the level is
currently turned on, the entities previously deleted on 
that level are recovered and displayed.

ALL - to recall all previously deleted entities and 
display them on the screen. Mask on the entities for 
recall in one of the following ways:

 - by retrieving all deleted entities (ALL).

 - by retrieving deleted entities by type using a 
   Selection Mask option (BY TYPE).

 - by retrieving all deleted entities, with the exception 
   of those specified using the Selection Mask menu, and
   displaying them on the screen (EX TYPE).

All of the specified entities in the database are recalled
and displayed, if appropriate.
