{{Function
Added by NVSE 4. Used to repeat a script block for each entry in a collection. The collection may be either a container, [[Array Variable|array]] or [[String Variable|string]]. In the case of a container, an entry is a [[Ref Variable|ref]] to an item in its inventory. For an array, each entry is a stringmap with two fields, <b>"key"</b> and <b>"value"</b>. For a string, each entry is a string containing a single character.

Within foreach loops, the command <b>continue</b> may be used to skip any remaining loop code for that entry, and move on to the next. In the same context, the command <b>break</b> may be used to end the loop immediately, ignoring any remaining code and entries.
