24470 - How do I use the SAS Code node in the SASŪ Enterprise Miner? 5.x series to perform my own data manipulations? You can create a SAS data set from within the SAS Code node by naming the data set in the DATA step that creates it. For example, if you are using a DATA step to create a data set, then name the data set in the DATA ... http://support.sas.com/kb/24/470.html, 19KB |
