SAS/Warehouse Administrator Metadata API- P56: The operating system and SAS version that are associated with a given host are now available through the WHHOST property. For example, you can write a SAS/Warehouse Administrator add-in that reads the host metadata that is associated with a given data store and then uses these values to generate code that is appropriate for the operating system and SAS version. | 272 273 Sample Metadata API Code Appendix Overview 273 Read Metadata Code Sample 273 Write Metadata Code Sample 277 Appendix Overview This appendix contains SCL code that uses the metadata API to access SAS Warehouse Administrator metadata. For longer examples see the sample metadata API applications in the catalog. That catalog includes the BLDPAGE program which reads metadata and outputs it in HTML format.
