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:

proc iml;
start main;
   em1=10; em2=11; em3=12; em4=13;
   call execute(concat("s=sum(0" , rowcatc(",em1":",em4"),");"));
   print s;
finish;
run main;
quit;

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,

Ian.
