I know my question is cheap but I really need your helps and I appreciate all who give tips to me. I recently installed Gams for optimization purposes through this https://www.youtube.com/watch?v=Mx_tYI3wyP4 and it was successful. I desire to use gams studio but I can not run it. Unfortunately, I am new to ubuntu and I just know that to run an application, I should type its name in command line and hit the Enter but it dose not work to me. When I run gams in my terminal I get the followings which show my installation is perfect:

Now I want to use gams studio to code. I read in its documentation page that gams studio is installed during gams installation. But I can not run it and i get the following message
