I also think the description is misleading. You're filtering a list, ie you're return values that remain after applying the filter. Here you're taking them out. Why not call it:

ContractList ( theList ; theValue ; theNewList ; theIteration )

Notice that I've reversed the first two and renamed the params for clarity.

A great variation is having the list with only the value that "begins with"

beginsWith = Left ( $val ; $length )
beginsWith ≠ Left ( $val ; $length )
