: How do i use an interger in a string?

: What i mean is that; i'm making a kinda game where you fiddle with a population of people and control things they do! So that you can use cheats i want to use a string then an integer... So it would be like this (what would be typed to cheat):

: Populate: 7889

: This setting the population to 7889 (if you need to know it sets a hidden spinedit.value to this number) i want to check it says 'populate: ' then if thats there it checks the int after it and sets the spinedit.value to that!

: At the momment i have but i dont know what to do with anything about the int:

: procedure TForm1.Edit1KeyPress(Sender: TObject; var Key: Char);
: begin
: IF edit1.text = 'populate: ' then
: spinedit1.value := ???
: else
: label1.caption := 'Cheat Unkown or not sufficent information';
: end;

: Please could you help me set spinedit1.value to a number following 'populate: '?

: Thanks ;), Joey

From the top of my head, so you'll have to check if the syntax is really correct ;-) ...

  P, ErrCode: integer;
  if LowerCase(Copy(Edit1.Text, 1, 10) = 'populate: ' then begin
  Val(Copy(Copy(Edit1.Text, 11, Length(Edit1.Text), P, ErrorCode);
  if ErrCode := 0 then  
    Spinedit1.Value := P;
    Label1.Caption := 'Cheat Unkown or...';
