An executable macro called CBRXLCS is used to invoke the functions provided by LCS External Services. The macro expansion sets parameter values in the LCS External Services parameter list (LCSPL), which is mapped by the CBRLCSPL macro, retrieves the entry point for LCS External Services, and branches to perform the requested function. See CBRXLCS macro interface for the CBRXLCS macro usage, return and reason codes, and parameter list.

This section provides the syntax, required and optional parameters, and return and reason codes for each CBRXLCS function.
