INTRODUCTION Executing GAMBIT Commands © Fluent Inc., Jul-04 1-1 1. INTRODUCTION GAMBIT is designed for use with a mouse, but most of its operations can also be exe- cuted by means of commands entered from the keyboard or from a journal file. The pur- pose of this manual is to summarize the purpose, format, and use of such commands. 1.1 Executing GAMBIT Commands GAMBIT commands can be executed from either of two sources: Keyboard Journal files To execute a GAMBIT command from the keyboard , you must input the command on the Command line and press Enter . (The Command line is located immediately below the Transcript window on the GAMBIT GUI.) GAMBIT automatically checks the syntax of any keyboard command and returns an error message in the Transcript window if the syntax is incorrect or if the command constitutes an illegal operation. In some cases, such error messages include a list of allowable keywords and/or input variables. Journal files are text files each line of which constitutes a comment or GAMBIT com- mand. The syntax of GAMBIT journal-file commands is identical to that of commands entered by means of the keyboard. For a complete description of GAMBIT journal files and their use, see Section 4.1.6 of the GAMBIT User’s Guide.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
