The messages windows displays information from programs that output through a DOS filter, for example GREP. You can scroll through the output messages or choose to edit the program line referenced in the message.
Editing a program line referenced in a message
Select the message you are interested in and double-click or press ENTER. Your cursor will jump to the program line in the source code that is referenced by the message in the messages window.
By default the message window will close when your cursor goes to the program line in the source code. If you prefer the messages window remain open, deselect Close on Go To Source option in the Preferences dialog box.
Tracking program lines
Select the message you are interested in and press SPACEBAR. If Auto Track Source is selected, referenced program lines are highlighted in your source code automatically.
