The easiest way to run Lingo is to create an input file <file.lng> with 
your LP program and, when prompted by Lingo, type:

:	take file.lng

It will run the program and display the result on the screen and/or 
will store it in the file <file.out> specified in your input file.

For details refer to the examples given on the web site.
