Use of memtype with kill

Kill deletes all SAS files along with the datasets in a particular library. For example, consider a user had assigned a format for display in report and the user also had made use of kill statement to kill the work library. The kill statement which is used at the end of the code not only deletes the dataset in work library, it also washes away the formats of the report because of which the report will no longer have the format that the user had assigned. Hence if the user wants to delete only the datasets then it is better to make use of memtype option which will preserve all other sas file and will kill only the dataset member type.

proc datasets lib=work kill memtype=data;
run;
quit;
