In SAS Enterprise Guide 8.4, how to run selected code will NOT replace the previous output from running the full program. In SAS EG 7, when I run selected code, there is a prompt to ask if you replace or save as a different name.
So what is it that you don't want to replace? Your SAS log or your results or both? The option you refer to is gone in EG 8 but it is possible to keep a log history by having a project log.
