This variable allows you to specify a set of directories that the runtime will search when attempting to locate a shared library. The format of the value is the same as that allowed for FILE_PREFIX. You can set SHARED_LIBRARY_PREFIX in the configuration file, environment, or programmatically with the SET verb.
The default value on Windows systems is empty.
The default value on UNIX and Linux systems is /opt/acucorp/xxx/lib:/opt/acu/lib. This helps the runtime find aclnt.so (or aclnt.sl) when the operating system's shared library environment variable (e.g., LIBPATH, LD_LIBRARY_PATH, SHLIB_PATH, etc.) is not set.
