The Message Window

While MPL is running it can send various progress information to a message window. Before solving or parsing a model you can open the message window by choosing Message Window from the View menu. If you want you can leave this window open while you are working in MPL as it will be updated automatically when you run your model.

What information is sent to the window will depend on which options are selected in the Message Window group of the MPL Environment Options dialog box.

• Status window messages: Sends all the status messages that are displayed in the topmost area of the Status Window to the Message Window.
• MPL input lines: Sends all input lines from the MPL model file to the Message Window.
• Performance statistics: Sends performance statistics on parsing in the MPL model file to the Message Window.
• Memory Usage statistics: Sends statistics on the MPL memory usage to the Message Window.
• Warning messages: Sends all warning and error messages from MPL to the Message Window.
• Database Connection: Sends all messages concerning connection to databases to the Message Window.
• SQL statements: Sends all SQL statements that are issued when importing and exporting data through the database connection to the Message Window.
• Solver Iteration Log: Sends all iteration log information from the solver to the Message Window.
