As described in Chapter 19, SAS/IML enables you to store and load matrices and modules in your own STORAGE library. The STORE, LOAD, REMOVE, and RESET STORAGE commands apply to the STORAGE library and enable you to store and load user-defined matrices and modules.
In contrast, the IMLMLIB library contains predefined read-only modules. You cannot store additional modules in IMLMLIB.
You can use the SHOW command to obtain information about both the IMLMLIB and the STORAGE libraries, as described in the following list:
SHOW OPTIONS displays the settings of the STORAGE and IMLMLIB libraries and shows whether the libraries are open.
SHOW STORAGE displays the contents of the STORAGE library.
SHOW IMLMLIB displays the contents of the IMLMLIB library.
SHOW MODULES displays the names of the modules that are loaded in the current environment. These include modules loaded from either library and modules defined in the current session.
