You can use the TERSEO parameter to control the amount of output LINGO generates.  There are four settings available:

TERSEO

Description

1

Verbose—Causes LINGO to display the maximum amount of output, including full solution reports.

2

Terse—Less output than Verbose, with full solution reports suppressed.  This is a good output level if you tend to solve large models.  LINGO also suppresses Export Summary Reports generated when exporting data to spreadsheets or databases.

3

Errors Only—All output is suppressed, with the exception of error messages

4

Nothing—LINGO suppresses all output.  This level may be useful when taking advantage of the programming capabilities in LINGO, in which case, you will add statements to your model to generate all required output.

The default setting for TERSEO is 1, or verbose mode.
