Why will this not compile under Delhpi 3?  The error is on the first line, Incompatible types, Integer and TDateTime.

Case DayOfWeek(Date) of
2 {Monday} : System.Assign(FileHandle,'Monday.txt');
5 {Thursday} : System.Assign(FileHandle,'Thursday.txt');
else : System.Assign(FileHandle,'others.txt');
end;

On my D4.02 the case line compiles just fine.

However, there is a syntax error, also change date to SYSutils.date to remove any name collision:

Change it to this:

Case DayOfWeek(SysUtils.Date) of
    2 {Monday} : System.Assign(FileHandle,'Monday.txt');
    5 {Thursday} : System.Assign(FileHandle,'Thursday.txt');
    else
   System.Assign(FileHandle,'others.txt');
    end;

This procedure I made from your code sample compiles OK:

procedure test;

var
  FileHandle : TExt;

begin
Case DayOfWeek(SYSUtils.Date) of
    2 {Monday} : System.Assign(FileHandle,'Monday.txt');
    5 {Thursday} : System.Assign(FileHandle,'Thursday.txt');
    else : System.Assign(FileHandle,'others.txt');
    end;
end;

Cheers,

Raymond.

I'm not sure, though this example compiles fine:

procedure TForm1.FormCreate(Sender: TObject);
var
  S: String;
  F: File;
begin
  Case DayOfWeek(Date) of
    1 {Sunday}   : S:='Sunday.txt';
    2 {Monday}   : S:='Monday.txt';
    3 {Tuesday}  : S:='Tueday.txt';
    4 {Wednsday} : S:='Wednsday.txt';
    5 {Thursday} : S:='Thursday.txt';
    6 {Friday}   : S:='Friday.txt';
    7 {Saturday} : S:='Saturday.txt';
    else
                   S:='Else';
  end;
  System.Assign(F,S);
end;

If this doesn't help, try to say where your problem occurs.

But you could event though try to replace the case sentence with:
  Case DayOfWeek(TDateTime(Date)) of

(It might also be an error, where you previously declared a 'Date' variable as an Integer overriding the system Date function.)

Regards,
Williams

Your solution did not work.  Same problem...  However, you did get my brain juices flowing, and I did discover that the following DOES work...

    Case SysUtils.DayOfWeek(SysUtils.Date) of

thanks.
