I have two sas datasets that contain the same information but in different variable names.  I am having one of those moments where I cannot see how to do this.  Any help is appreciated.

Data  DS1;
  INPUT A $ B $ C $ ;
 Cards ;
  Small Tike  Red
  Med   Bike  Blue
  Large Bike  Red   ;;

Data DS2 ;
 INPUT X $ Y $ Z $ ;
  Cards ;
  Small 10.99 1yr
  Small 20.99 2yr
  Large 50.00 1yr
  ;;

Data AllDS ;
  Merge  DS1  DS2 ;
  (  Need Var A Merged and Var X -  The fields are alike but the variable name is different) ;
    By ? ;

Should come out

Small Tike RED  10.99 1yr
Small Tike Blue 20.99 2yr
Med   Bike Blue
Large           50.00 1yr

Thanks   Lizette

Use the data set option RENAME= to rename one (or both) of the input
variables.

You are commended for providing ready-to-use test data.

SQL can do this job without renaming or pre-sorting:

   proc sql;
   create table AllDS as
    select coalesce(ds1.a,ds2.x) as ax, b, c, y, z
     from ds1 full join ds2
      on ds1.a = ds2.x
    order by ax desc;
   quit;
