Allow PROC SORT to output multiple datasets Status:New SuggestionSubmitted bymkeintzon06-01-202101:17 AM 18 Comments (18 New) Frequently a SAS programmer needs to both sort and divide a dataset. Typically these tasks are satisfied via a two stage program: (1) divide the dataset, (2) ...
The COPY Procedure The following options are new or enhanced in the COPY procedure and the COPY statement in PROC DATASETS: q The FORCE option enables you to use the MOVE option for a SAS data set that has an audit trail. q The CLONE option now copies the data representation and encoding...
The hash OUTPUT method will overwrite a SAS data set, but not append. That can be costly. Consider voting for Add a HASH object method which would append a hash object to an existing SAS data setWould enabling PROC SORT to simultaneously output multiple datasets be useful? Then vo...
