You should provide example data of the two data sets and what you expect as a result. Data is best in the form of a data step.   Note that if the variable in two or more data sets for Merge or Set with the same name has different types then SAS will throw an error and not allow any execution of the data set. You will need to either rename the variable so they don't have the same name or in a prior step go the dance to create a different data set with the proper type variable.   Here's an example of "fixing" a character variable that should have been numeric: data have; input x $; datalines; 1223 456 ; run; data want; set have(rename=(x=oldx)); x=input(oldx,f5.); run; The numeric to character case involves a PUT statement with the proper format. ...

Try running each of the programs (with a RUN; statement at the end of each), and see what the results are.   The SET statement reads observations from a SAS data set.  You will 100% need to learn that. ... View more

And, please, don't code all upcase, because it reduced readability. Code is best posted by using the running-man icon, to preserve formatting. ... View more

Interesting homework.   So you need one data step to create the datasets "bio" and "personal" and a second step to merge them to create "full". And to control which variables are written to each dataset, you will need one of the keywords already mentioned by @Reeza    ... View more
