| [[Category:FloatNamedArraylist methods|ItemByNumber property]] | |
| <!--DPL?? Category:FloatNamedArraylist methods|ItemByNumber property: Value of item selected by item-->
| |
| <p>
| |
| ItemByNumber is a member of the [[FloatNamedArraylist class]].
| |
| </p>
| |
| | |
| This ReadWrite property returns or sets the FloatNamedArraylist item that has
| |
| the specified item number.
| |
| Item number is ordinal, so
| |
| ItemByNumber(3), for example, identifies the third item in the
| |
| numerically ordered FloatNamedArraylist.
| |
| ==Syntax==
| |
| %item = %fnamrayl:ItemByNumber(number)
| |
| | |
| %fnamrayl:ItemByNumber(number) = %item
| |
| ===Syntax Terms===
| |
| <dl>
| |
| <dt><i>%item</i>
| |
| <dd>A variable of the same
| |
| type as specified on the ''%fnamrayl'' declaration
| |
| to contain the value of the specified ''%fnamrayl'' item.
| |
| Or a variable or value of the same
| |
| type as specified on the ''%fnamrayl'' declaration
| |
| to be assigned to the specified ''%fnamrayl'' item.
| |
| <dt><i>%fnamrayl</i>
| |
| <dd>A FloatNamedArraylist object.
| |
| <dt><i>number</i>
| |
| <dd>A whole number greater than 0 to identify a ''%fnamrayl'' item
| |
| by its position in the FloatNamedArraylist.
| |
| If ''number'' is greater than the number of items in ''%fnamrayl'',
| |
| or if it is less than or equal to zero, the request is cancelled.
| |
| | |
| </dl>
| |
| ==Usage Notes==
| |
| <ul>
| |
| <li>If the ItemByNumber property is being set and there is already an item
| |
| on the FloatNamedArraylist that has the specified item number (position),
| |
| that item is replaced.
| |
| | |
| If the ItemByNumber property is being set and there is no item on the
| |
| FloatNamedArraylist that has the indicated item number, the item is added.
| |
| | |
| If the ItemByNumber property is being retrieved and there is no item on the
| |
| FloatNamedArraylist that has the indicated item number,
| |
| the result is one of the following actions:
| |
| <ul>
| |
| <li>The request is cancelled if the
| |
| [[UseDefault (FloatNamedArraylist property)|UseDefault]] value is <tt>False</tt>.
| |
| <li>The [[Default (FloatNamedArraylist property)|Default]] value is returned if the
| |
| UseDefault property is <tt>True</tt>.
| |
| </ul>
| |
| <li>[[Item (FloatNamedArraylist property)|Item]] lets you retrieve or
| |
| set an item using its item subscript number.
| |
| </ul>
