The Problem is in Dmwrite Statement ...
It won't write the Structure directly..
Try to write each member of your record independently
..
For Ex:
offset = 0;
error
=DmWrite(textPtr,offset,(CharPtr)&fin->indicator,
sizeof(fin->indicator));
offset+=sizeof(fin->indicator);
for next member increase the offset accordingly ...
