Use the AMPL command pane (also called the Console) to define, solve, analyze, and modify optimization models by entering the commands described in the AMPL book and used by all versions of AMPL. This pane is initially in the middle when the IDE opens.

Type commands at the “ampl:” prompts that appear in this pane. Your typing and AMPL’s responses scroll upwards and you continue to enter commands, just as they do in the command-line interface to the classic version of AMPL.

Use the up-arrow and down-arrow keys to recall previous commands to the “ampl:” prompt. You may edit the command currently showing. Press Enter to send the (possibly edited) command to AMPL.

If an error occurs when using a command that reads a file — such as model, data, or include — the IDE creates a link in each error message that AMPL returns. Click on an error message link to highlight the line where the error occurred; the file containing this line is automatically opened and its editor window is brought to the front of the File Editing Pane if necessary.
