substr the last few letters

[iusing]

I would like to know how to get the final few letters of a string?

You could always use substr using the length function to get the variable's starting point. e.g.:

data want;

  set sashelp.class;

  last3chars=substr(name,length(name)-2);

run;

If you want last n letters then you should start from length(of your variable)-n+1.

data want_last_2;

  input AA $;

  newaa=substr(aa,length(aa)-1);

cards;

;

proc print;

run;
