I know longer have SAS 9.3 installed, and I don't remember the details from that era, but the current SAS/IML documentation answers your question. In SAS 9.4 you can %INCLUDE the robustmc.sas file and then use the functions. The example shows the details, but it begins with
%include sampsrc(robustmc); /* define graphing modules */
proc iml;
load module=_all_; /* load graphing modules */
