Do it this way and it will work and it's much easyer to understand:
program Project1;
const
    Key       =  ['O'..'9', '*', '#' ];
var
    userinput : char;
begin
  Read(userinput);
  if userinput in Key then
    WriteLn(userinput,' is  in set')
  else
   WriteLn(userinput,' is not in set');
  ReadLn;
end.
