For example, if a dataset A contains 10 records and dataset B contains 10 records. I want combined dataset would contain 20 records. Create data sets in SAS. #N#Input Data Sets.
To avoid reading all the records, you can append the second file to the first file by using the APPEND procedure: proc append base=year1 data=year2; run; The YEAR1 file will contain all rows from both tables. Note: You cannot use PROC APPEND to add observations to a SAS data set …

The BASE= data set option is reserved for the larger of the two data sets with the DATA= option for the smaller data set. Essentially, the APPEND ...

You could use PROC APPEND. If the BASE table doesn't exist then it will create it. Otherwise the observations are appended. proc append force base=final_table data=table&i; run; Note that this will require that the datasets have the same columns.
