A number of calls return lists of symptoms. These are represented as an array of array references. Each subarray consists of four elements, each of which has the following significance:
$x = type (INT) $x = certainly (FLOAT) $x = object (STRING - class::instance) $x = event/symptom name (STRING
You can gain access to the elements by using one of the following syntaxes:
$list[ $record_number ] -> [ $field_number ]
$listref -> [ $record_number ] -> [ $field_number ]
The first syntax is used where the list is held in an array variable. The second syntax is used when the list is held in an array pointed to by a reference.
