KeyPressed procedure

[Jachimo]

Hello
I am new to Delphi and am having trouble implementing the KeyPressed procedure. On the Internet I find procedures or functions that respond to 1, 2, or several keys, but I have not found anything that would respond to any key. (Equivalent to the Pascal KeyPressed procedure).
I attach a program fragment in which I want to apply the procedure.

.....
begin

.....

Rx := expr;
if Rx = 0.0 then begin
Memo1.Lines.Add( 'Check why Rx = zero ');
Memo1.Lines.Add( 'Press any Key');
repeat
until KeyPressed);
halt
end;

.....

end;
end.

Please help.
Regards

If you want to capture any key pressed on any of the controls on a form, then you have to set the form's keypreview property to True.

This whole thing looks odd. You typically don't do console control with Windows forms. OP what are you trying to accomplish?
