Andrew, Thanks.

Corrected now. Now, .val for .value.

Running perfectly in glpk4.44.

Interested? See the example below copy and paste to the
transp_csv.mod. This model from Xypron.

solve;

table tab_result{(i,j) in K} OUT "CSV" "result.csv" :
  i ~ plant, j ~ market, x[i,j] ~ shipment;

 table ts {i in I} OUT 'CSV' 'supply.csv' :
 i ~ PLANT,
 supply[i].val ~ SUPPLY_VAL,
 supply[i].lb ~ SUPPLY_LB,
 supply[i].ub ~ SUPPLY_UB,
 supply[i].dual ~ SUPPLY_DUAL;

table td {j in J} OUT 'CSV' 'demand.csv' :
 j ~ MARKET,
 demand[j].val ~ DEMAND_VAL,
 demand[j].lb ~ DEMAND_LB,
 demand[j].ub ~ DEMAND_UB,
 demand[j].dual ~ DEMAND_DUAL;
