I am having a table old with variable Test with length=20 now i want to increase the length how can i do it . can we do by proc datasets procedure
data class; set sashelp.class;run; proc sql; alter table class modify name char(100); quit;

No. Proc datasets only changes metadata attributes and a change to a variables length means that spaces physically either have to be added or removed from each record.
Edit: Art is right, there is no way to do it using proc datasets.
if using data step;
data want;
length sex $100.;
set class;
run;
