I have created a typed file, but when I try to access the typed file to read from it I get an I/O error 103.  Can someone tell me what I'm doing wrong?

Error 103 is a "File not open" ... probably a matter of either forgetting to close it after the last edit or you're not opening it correctly. Try this:

Var MyFile: File of MyType
   thefilename:string;
begin
Try
 TheFilename:='My file name here';
 assignfile(MyFile,thefilename);
if FileExists(thefilename) then
 Reset(Myfile)
Else
  Rewrite(Myfile);

 /// this checks to see if the file exists and opens it accordingly, either as a new file or a file to be edited.


Finally
  Closefile(myfile);
 end;
