To manage SAS files, it is quite easy because we can make use of the powerful PROC DATASETS procedure, which is specially designed for SAS file management uses. With this utility procedure, we can append SAS data sets, copy and move SAS files from one library to another library, rename ...
You can have multiple RUN groups within a particular invocation of PROC DATASETS. Here is an example of several RUN groups within a single invocation of PROC DATASETS: proc datasets library=sgflib; modify snacks; format price dollar6.2 ; informat date mmddyy10.; run; append base=snacks data=...
