I just want to convert all the strings in one variable 
into integers. e.g., the variable is grade_school 
(current grade in school) and the variable column has 
"2nd" "5th" etc., and I want to make it "2", "5" by
issuing just one command.

-destring- with the -ignore()- option does it. Try this:
 
   clear
   input str4 ns
   1st
   2nd
   3rd
   4th
   5th
   10th
   end
 
   destring ns , generate(n) ignore("s, t, n, d, r, h")

Hope this helps
