DL4LUST is a search path used to locate both data files and program files. DL4LUST is an environment variable or Windows registry entry similar to LUST under UniBasic, but using spaces to separate paths rather than colons. DL4LUST has both the strengths and weaknesses of LUST. For example, it is possible to kill a file, yet have the file seemingly remain (when there are two files of the same name in different search directories). It is also possible to build a file when the file already exists (in a secondary search directory). The multiple directory searches needed by DL4LUST can cause substantial performance degradation, especially when accessing files over a network. Using LUMAP instead of DL4LUST avoids these problems. DL4LUST was introduced in dL4 version 5.
