to store the sixth data point from \data into the postscript object
/sixth you may proceed as follows:
\readdata{\data}{simon.dat}
\pstVerb{
1 dict begin
/i 5 def %array indices are zero based
/D {} def %locally neutralise data separator `D'
[\data] [ exch dup
i 2 mul get exch i 2 mul 1 add get ]
end
/sixth exch def
sixth == %print to terminal
}
