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 (see Item (ArrayList property)), the Item method for Stringlists is not settable. To set a new value for a Stringlist item, use the Replace (Stringlist function).
  • 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
    
  • Methods are available to retrieve just the first or just the last item in a Stringlist. See FirstItem (Stringlist function) and LastItem (Stringlist function).
