If your source code has syntax errors, the IDE lists them in the Output window. The error message is displayed in blue underlined text and is linked to the line in the source code that caused the error. You can save the messages in the Output window to a file. You can also customize the window by setting color and font size, setting a limit on the window history, and so on.
