writeln() converts the ordinal value to the value name and if the entry
is not found, the 107 error is raised.

This program below crashes because the value 12 is not in the enum. I was curious though,
how does it know this? Does it have to do a linear search through the enum to find the
value? I know "succ" fails at compile time because the enum has assignments but
how this works at runtime is another question.
type
Fruit = (apple = 10,
banana,
pear = 20,
citrus);
var
f: Fruit;
i: Integer;
begin
i := 12;
f := Fruit(i);
writeln(f);
end;
