You should be able to declare an indexed collection of sets, for example:
set BaseSET;
set SetColl {BaseSET};
param DataVals {s in BaseSET, t in SetColl[s]};
Each of the sets in the collection may be given different numbers of
elements. For example the data file could contain:
set BaseSET := a b c ;
set SetColl[a] := ABD KDL ;
set SetColl[b] := G H LKM H KI ;
set SetColl[c] := ZZ YY XX ;
SetColl can be used similarly to index parameters, variables, constraints,
sums, and the like.
