Passing data to GAMS

In the Delphi program CSV files are created which contain the data to be passed.  These CSV files are written by code such as

   AssignFile(Fiwrite, 'distancetbl.csv');

   Rewrite(fiwrite);

   write(fiwrite,'fromdelphi');

   for j:= 1 to 3 do

      write(fiwrite,',',stringgrid1.cells[j,0]);

   writeln(fiwrite);

   for i:= 1 to 2 do begin

      write(fiwrite,stringgrid1.cells[0,i]);

      for j:= 1 to 3 do

              write(fiwrite,',',stringgrid1.cells[j,i]);

      writeln(fiwrite);

   end;

   closefile(fiwrite);

which writes the distance matrix as stored in stringgrid1.
