The IMLMLIB library is a catalog residing in the SASHELP directory. The catalog contains one entry of type IMOD for each module. Each entry is a module stored in its compiled form.

The SAS/IML source code that defines the modules is available in the catalog SASHELP.IML. There is an entry of type SOURCE for each module. You can view the source code in the program editor window under DMS by using the COPY command and specifying the four-level name:

SASHELP.IML..SOURCE

The source code is generally followed by examples of its use.

The source code can be edited for customization or enhancements, and can be included in other IML applications. The modules also illustrate a variety of IML features that can be used to solve more complex problems.
