/column names are specified
for a given group/row; for  a  variable/column-wise scheme, one or two
coefficients and their  group/row  names   are specified for   a given
variable/column.  We do, however, still require that in a group/row-wise
storage scheme, the names of all the  variables/rows <I>which appear
in linear elements</I>
are  completely specified before  the coefficients
are  input.  Similarly,  in a variable/column-wise storage scheme, the
names of all the groups/rows <I>which have a linear ele
