I don't think there is a way to do this without using 'call execute',
which will tend to make things rather ugly. For example:
em1=10; em2=11; em3=12; em4=13;
call execute(concat("s=sum(0" , rowcatc(",em1":",em4"),");"));
Perhaps you would be much better off not to use a series of scalars, but
to keep the values in a vector.
Hope that helps,
