Copy the program below and paste it into the Program Editor window (or issue the command
copy sashelp.oltutor..source). Then submit
the program. In the output, notice that the variable Date appears
only once in the data set.
data sasuser.merged;
merge work.adsort work.strsort;
by id;
run;
proc print data=sasuser.merged;
run;

Work.Adsort and Work.Strsort were created
in a previous practice. If you haven't created these data sets,
return to the practice and create them
before proceeding here. |
-
Recall the program. Add a data set option to rename the variable
Date in Work.Adsort to AdmitDate.
Add another data set option to rename the variable Date in
Work.Strsort to VisitDate.
-
Resubmit the program and view log messages about the DATA step. Scroll through
the output. Note that both renamed variables now appear in the data set.
Return here and select Next.
