how to keep only the last column in the dataset

[jdk123]

is there a shortcut to keep only the last column in the dataset?

for instance, keep last_column

Thanks,

[data_null__]

If we assume that means the variable with the largest value of VARNUM then...

[pre]
42 proc sql;
43 select name into :lastName separated by ' '
44 from dictionary.columns
45 where libname='SASHELP' and memname='CLASS'
46 having varnum eq max(varnum)
47 ;
NOTE: The query requires remerging summary statistics back with the original data.
48 quit;

49 run;
50 %put NOTE: LastName=&lastname;
NOTE: LastName=Weight
[/pre]

Use LASTNAME in a KEEP data set opion.
