In addition to [[#Pascal|standard Pascal]], one may explicitly specify an index: |
|||
<lang Delphi>type |
<lang Delphi>type |
||
fruit = (apple, banana, cherry); |
|||
| ⚫ | |||
Note, explicit indices ''have'' to be in ascending order. |
|||
| ⚫ | |||
You can also just specify explicit indices for ''some'' items. |

Note, depending on the <tt>{$scopedEnum}</tt> compiler switch (as of definition time), enumeration type members are identified via the type name prepended. |
|||
Additionally, enumeration types can be passed to <tt>write</tt>/<tt>writeLn</tt> producing the Pascal (source code) identifier. |

Enumeration is done by creating a cell array (a.k.a set) of objects, where the numeral of the object is its index in the 1-based cell array. The cell array structure can contain any type of data structure including other cell arrays, and all members don't have to be the same data type. |

Standard Pascal as per ISO 7185 only allows contiguous lists of identifiers as enumerated type definitions. |
|||
| ⚫ | |||
An explicit index may not be specified, but [[#Delphi|Delphi]] and [[#Free Pascal|Free Pascal]] allow this. |
|||
However, it is guaranteed, that the <tt>ord</tt>inal value will correspond to the member’s position in the list (<tt>0</tt>-based). |
