I have created a count field (XCNT) to serially count those MRNs with more than one record (e.g. MRN #104132).

TABLE FILE CRAZY
HEADING CENTER
" Patients Given Troponin Injection Prior to Admission "
" Date Created: &DATEMtrDYY "
" "
PRINT
EDP 
COMPUTE XCNT/I9 = IF MRN NE LAST MRN THEN 1
     ELSE IF MRN EQ LAST MRN AND EDP EQ LAST EDP THEN XCNT + 1
     ELSE IF MRN EQ LAST MRN AND EDP NE LAST EDP THEN 1
	 ELSE XCNT;
NAME
BY MRN
END

-*
As the output captioned below indicates, I am not getting
a count I am looking for:
MRN EDP XCNT NAME
104132 7327202 1 MONTGOMERY,JOHN E
7335621 1 MONTGOMERY,JOHN E
135419 7285749 1 WILSON,JESSE
141933 7310570 1 VINES,LINDA POWELL

174878 7257600 1 SCOTT,PHILLIP JORDAN
175521 7325633 1 ROSENKOETTER,ROBERT GENE

I am trying to get this output:
MRN EDP XCNT NAME
104132 7327202 1 MONTGOMERY,JOHN E
7335621 2 MONTGOMERY,JOHN E
135419 7285749 1 WILSON,JESSE
