Explanation

In IMS DL/I, command code 'L' (Last) forces IMS to find and retrieve the last segment that satisfies the SSA (Segment Search Argument) criteria. Command code 'F' is for First, 'D' is for Delete, and 'C' is for specific segment retrieval. The L command code is used when you need to navigate to the last qualifying segment in a hierarchical database.
