Hello this is my 2nd/4 questions: I am trying to understand the named question above. I am posting it below for convenience: Renaming (in SAS) some variables of 2 datasets before horizontally merging them. When is it necessary? How to do that within the merging data step itself? I am expected to format my answers by including the following: a) find out, for each issue, between 3 and 5 interesting documentation sources (eg SAS User's manuals, SAS course notes, archives of the SAS-L list, forums like SAS communities, SUGI papers, blogs on SAS, courses offered on university sites,...) explaining how to deal efficiently with this issue b) for each issue, give all the possible answers, explaining their relative characteristics and advantages, indicating the sources where the information was found. c) for each issue, the final synthesis should be very clear, proofread and potentially useful for people looking for explanations about the way to deal with the data management issues at stake, using SAS. It implies that, for each issue, the assignment should start with a brief explanation of what the issue is, then explain how to deal with this issue, and end with at least two short examples (easy to understand and to replicate) with comments between /* */. I appreciate comprehensive help, as these answers will enable better understanding and better performance on my upcoming exam. Kind regards!
