Since numerous ELEC blocks may appear in an APBS input file, it can be difficult to keep track of them all. It is possible to assign an optional name to each ELEC block to simplify the organizational process. This syntax has the form

   ELEC name {id}
       ...

where ELEC is the start of the ELEC block and {id} is an alphanumeric string denoting the "name" of the calculation block.
