Retrieve value of Stringlist item (Stringlist class)


This method returns the current contents of a specified Stringlist item.

The Item method accepts one argument and returns a string result.

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.
  • There are optimized methods available to retrieve just the first or just the last item in a Stringlist. See also:

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
