The Save As command allows you to save the contents of the active window under a new file name. When issuing the Save As command, you will be presented with a dialog box that resembles the following:

You can enter a new file name in the File name edit box, or select a file name from the list of existing files by double-clicking on it. If you do not specify a file extension, LINGO will append the extension of the default model format to the name. If you want to prevent LINGO from appending an extension to the name, place the file name in double quotes.

Press the Save button to save the model, the Cancel button to exit without saving, or the Help button for assistance.

You may select a different file type from the Save as type list box. If your model has special fonts or embedded objects, you must save it using the LG4 file format to preserve them. The LG4 format is a special binary format readable only by LINGO. If you wish to create a text copy of your model, then use the LNG file format. For further discussion of the available file formats under LINGO, refer to the New command.
