We define an enumeration type.
For each element, Nim allows to specify its integer value and its string representation. Here, the integer value is implicit (starting from zero) except for DEL whose value must be specified. As we use the standard names for the elements, we don’t have to specify the string representation.
The integer value is obtained with function <code>ord</code> and the string representation with function<code>$</code>.
