Setting lbl caption from procedure

[xeonite]

Hello,
I'm using Delphi 6.0 Personal for my programming project at school. The goal is to create a small RPG.

The problem is today I tried to set a label caption from a procedure which looks like this...

procedure name(value1,value2,value3:integer);
begin
label.caption:='text';
end;

Now that gave me an error stating that label was an unknown identifier. I know what the problem is, but do not know a solution to it. How do I change the properties of that label from that style of a procedure. Also that procedure is called from a button click event and after doing several tasks, including changing several labels, calls another procedure.

Thanks in advance.

Just to add (is there an edit button I coudln't find it) I've figured out how to do what I needed. But a smaller question remains if I'm assigning an integer or a char variable to a caption of a label. Is there an easier way of doing it then converting to a string variable first?

(1) This would work if "label" is the name of the TLabel:

procedure name(value1,value2,value3:integer);
begin
  label.caption:='text';
end;

(2) To use an integer in a caption it must be converted to a string, so no there is no easier way:

   Label1.Caption := 'Item # ' + IntToStr(nItem);

This is part of Delphi's "strong typing."

Apparently that your procedure isn't a memeber of a form, thus you must use your label specifing a form that owns it i.e. Form1.label.caption := 'blah blah'.

Whenever I need to add an integer to a string, I use:
MyString := format( 'Some Text %d', [IntegerValue] );

I find this is faster than calling IntToStr and works for a lot of data types including other strings. You just replace the %d with another token. Look in the Delphi help for format and there's a help link showing the tokens for other data types.
