In addition to LUMAP and DL4LUST, dL4 uses the LIBSTRING runtime parameter to locate programs and libraries. It is a runtime parameter which contains a space separated list of directories to search when linking, CALLing, or CHAINing to program files. This value is returned by the debugger's STATUS UNIT command and by the Msc$(6) function. The OPEN statement does not use LIBSTRING to find data files.

Please refer to the appropriate Installation and Configuration manual for a discussion on configuring LIBSTRING.
