can't find file?

Ok, here's the deal. This program should  process a list of applicants: name number of cigarettes smoked each day, and weight. If they meet the criteria (numb > 10) and (wt > 180) then a message should be printed 'Accepted". If not, then a message should be printed 'Rejected' and also printed will be the reason why they're rejected. It should also print each applicant's name, number of cigarettes, and weight. (The 'Rejected'(+ reasons) or 'Accepted' should come after the name, cigarette# , and weight) For all 'Accepted' applicants, it should print the average number of cigarettes smoked daily and the average weight. Here's what I got sofar, but when I try to compile it, it gives me 'Cannot find file' on the reset(AppFile) line. I've created that file!

var name: string;
    numb: integer;
    wt: integer;
    AppFile: text;

procedure GETDATA (var AppFile: text;
                   var name: string;
                   var numb: integer;
                   var wt: integer);

  begin
    readln (AppFile, name);
    readln (AppFile, numb);
    readln (AppFile, wt);
  end; {GETDATA}

procedure POSITION (name: string;
                    numb: integer;
                    wt: integer);

    begin
      if (numb < 10) and (wt < 180) then
        writeln ('Accepted ');


      if not (numb < 10) and (wt < 180) then
           writeln ('Rejected ');
           writeln ('Your weight is more than the given weight ');
           writeln ('The number of cigarettes you smoke is over the limit ');
    end; {POSITION}

begin {main}
  assign (AppFile, 'AppFile2.dat');
  reset (AppFile);
  while not seekeof (AppFile) do
     begin
        GETDATA (AppFile, name, numb, wt);
        POSITION (name, numb, wt);
     end;
  close (Appfile)
end.

I don't know what compiler you are using because that error message seems strange.  

Here is the question.  Is the file in your compiler folder or directory?

You may have to specify folder that the file is in like the following line

assign(AppFile, 'c:\pascal\AppFile2.dat');


See if you can solve that problem first before considering the next section.

Comments on your coding:

In procedure GetData you don't need to use parameters.  You could use globals in this case unless you have been specifically told not to.  Similarly you don't need to use parameters in Postion as well.

If you do need to use parameters don't use the same names as the globals.  This can cause errors especially when debugging.  Use different names.  Here is Getdata with changes.

procedure GETDATA (var LocalAppFile: text;
                                      var Localname: string;
                                      var Localnumb: integer;
                                      var Localwt: integer);

begin
  readln(LocalAppFile, Localname);
  readln(LocalAppFile, Localnumb);
  readln(LocalAppFile, Localwt);
end;

I have used Local to indicate that these parameters are internal to this procedure only.  The syntax you use is up to you.
