EL: pass/reference data set?

["Earl Adamy" <eadamy@xxxxxxxxxx>]

When passing multiple series within the same data set, it seems both
wasteful and repetitive to require an input for each series:

    NyOpen(Open of Data7),
    NyHigh(High of Data7),
    NyLow(Low of Data7),
    NyClose(Close of Data7),
    SpOpen(Open of Data3),
    SpHigh(High of Data3),
    SpLow(Low of Data3),
    SpClose(Close of Data3);

Does anyone know if there is a way to pass and use a reference to a complete
data set rather than each of its data series? Something along these lines:

    NySet(Data7),
    SpSet(Data3);
    If Close of NySet > Close of SpSet .......
