Use the functions ParamStr(x) and ParamCount

In the FormCreate method, do something like:

Procedure TForm1.FormCreate(Sender: TObject);
var I: Integer;
    S: String;
begin
   For i := 0 to ParamCount-1 do
      S := ParamStr(i)
end;

And thats about it!

Let me know if you need more info!

hi PsychoFox, StuartJohnsen,

in addition to starts answer,

stuart:
you loose the last parameter,

the line
 For i := 0 to ParamCount-1 do
should be
 For i := 0 to ParamCount do

ParamStr(0) holds path and exeName of the program

PsychoFox

you should do what you want with the parameters

var
  ExeName : String;
  ToStart : Boolean;
  FOption : String;

Procedure TForm1.FormCreate(Sender: TObject);
    var I: Integer;
        S: String;
    begin
       For i := 0 to ParamCount do
       begin
          If i = 0 then ExeName := ParamStr(0)
          else
          begin
             If ParamStr(i) = '/Start' then ToStart := True
             else
                If ParamStr(i) = '/f' and i+1 <= Paramcount then FOption := ParamStr(i+1)
                else
                  { and so on ... }
          end;

    end;
