The DROP statement drops the specified
variable from the
access descriptor so that the variable is not available for selection when creating a
view descriptor. The specified variable in the
database remains unaffected by the DROP statement.
variable-identifier can
be one of the following:
-
the current SAS name for the item
-
the positional equivalent, which
is the number that represents the item, as specified in the LIST statement
-
the SYSTEM 2000
C-number of the database item.
For example, if you
want to drop the third and fifth items, submit the following statement:
drop 3 5;
If you are creating an access descriptor in
interactive line mode and want to mark an item as display that was previously marked as non-display with
the DROP statement, use the RESET statement for that item.
Note: If you drop a record, every
item in the record is dropped.
Note: If you use the RESET statement
for an item, the various attributes of that item are reset (such
as name, format, and so on) to their default values.
