proc tab and a difference coulmn

[robm]

I have a proc tab

option validvarname=any;
libname stdnt "E:\SAS\Data\Student";
libname robm "f:\robm";

proc tabulate data=ROBM.dump missing contents = ' ' format=COMMA6.0 S=[foreground=highlight.];
   class 'Reporting Year'n 'Responsible College'n 'Reporting Year'n;
   var 'Final Charge'n;
   keylabel Sum = " ";
   table  ('Responsible College'n ="")  all=Total , (('Reporting Year'n="Reporting Year" )*(('Final Charge'n = "")*F=COMMA12.0)) /
                  contents = ' ' misstext=' ' box={label="test"};
  run;

that gives

 

How do I get a 4^th column that is the difference of 2017/2018 – 2016/2017 values?

Either use proc report which allows referencing result columns in calculations or do all of the summary before, do the calculation in a datastep and use proc tabulate (or report or print) to display the calculated result.
