Content-Type: text/plain; charset=iso-8859-1

Do anyone know how to do a MODIFIED for a ARRAY element  in SCL ?
I have the following do loop:

ARRAY EMP(*) FIELD17-FIELD28;
  DO I = 1 TO 12;
       IF EMP{I}=_BLANK_  AND MODIFIED(EMP{I}) THEN DO;
......
 END;

The error msg reads :
ERROR:  Line 73â  Argument 1 of function MODIFIED must be a screen
field.

Field17-Field28  are defined as AF screen variables .

Thanks for anyone's help !!!
