Except (keyword)

From RemObjects Software

This is a Oxygene Keyword topic
Feel free to add your notes to this topic below.

The except keyword is used to mark the beginning of the block of instructions that handles an exception in the try statement. If the except block can process the exception, the program continues working.

With the first version, if the try block generates an exception, the except block is carried out. It is used for undertaking an alternative action, when something unexpectedly goes wrong.

try
  //statements
  except
    ShowMessage('Unknown error!');
  end;

The second version is similar to the first, but determines various actions for various types of exceptions:

try
  //statements
  except
    on E:Exception do begin
      MessageBox.Show('Found an error: '+E.Message);
    end;
  end;

The Exception Handling topic has more information for the try, except and finally options.
