u can use keep dataset option or keep statement to limit
the no of variables depending on ur requirement. if u want
process only those 5 variables, u can use keep dataset
option. if u want to limit d variables after d data is
processed u can use keep statement.
data new;
set old(keep=v1 v2 v3 v4 v5);
run;
or
data new;
set old;
keep v1 v2 v3 v4 v5;
run;
