Retrieve value of Stringlist item (Stringlist class)
Syntax
%string = sl:Item( itemNum)
Syntax terms
| %string | This longstring is to contain the contents of the sl item. |
|---|---|
| sl | A Stringlist object. |
| itemNum | The number of the item in the sl Stringlist. |
Usage notes
- All errors in Item result in request cancellation.
- Unlike the Item method for Collections, the Item method for stringlists is not settable. To set a new value for a stringlist item, use Replace.
Examples
- The following loop uses the Item method to display the contents of a Stringlist:
for %i from 1 to %list:count print %list:item(%i) end for
This could be accomplished much more easily with:
%list:print
- Under Sirius Mods Version 6.8 and later, the method name, Item, is not necessary on a Stringlist Item reference. For example, the previous program with Item references could be written as:
for %i from 1 to %list:count print %list(%i) end for
