Especially in free-format statements about properties of observations
it is worthwhile to use CLASSIFICATION structures which are partially
similar to those in the CLASSIFY operation.
A classification is defined as
CLASSIFICATION <name_of_classification> 
<list_of_values>: <value_or_statement> 
<list_of_values>: <value_or_statement> 
...
END
and the values of variables are classified by a special function
$CLASS(<name_of_variable>,<name_of_classification>).

Then, for example, purely verbal narrations of observations may be
created.
In such situations it is also good to collect selected or even all
descriptions to one edit field (by a MEDIT_SAVE specification).

These features are illustrated in the next example.
