Jean Hardy asked about two undocumented SAS-PC DM commands. The ones I know are: CDE - informs user what the largest memory block (out of conventional memory - below the 640K DOS limit) amount is. In other words, this should reflect the size of the graph, GLM model, etc. that could be run. I believe you should see a value around 240000 (bytes) with no S EMS and around 420000 with EMS. These values may vary. CDM - shows the load addresses (memory locations) of the SAS modules that have been used. If you are using EMS and know where the EMS paging is located, at least some of your display manager modules should be located in this EMS paging area. Some EMS software calls this paging area the "window" or "window address". These commands will work with EMS being used; indeed, they were designed to help SAS Inst. determine whether EMS was being properly used.
