Weegy: common variables with the same data but different attributes The way SAS handles these differences depends on which attributes are different: type attribute If the type attribute is different, [ SAS stops processing the DATA step and issues an error message stating that the variables are incompatible. To correct this error, you must use a DATA step to re-create the variables. The SAS statements you use depend on the nature of the variable. length attribute If the length attribute is different, SAS takes the length from the first data set that contains the variable. In the following example, all data sets that are listed in the MERGE statement contain the variable Mileage. In QUARTER1, the length of the variable Mileage is four bytes; in QUARTER2, it is eight bytes and in QUARTER3 and QUARTER4, it is six bytes. In the output data set YEARLY, the length of the variable Mileage is four bytes, which is the length derived from QUARTER1. data yearly; merge quarter1 quarter2 quarter3 quarter4; by Account; run; To override the default and set the length yourself, specify the appropriate length in a LENGTH statement that precedes the SET, MERGE, or UPDATE statement. ] (More)
