I am going to call a function (an external GAMS code) to my main GAMS code. In MATLAB, it is really convenient to call an m-file as a function (an external m-file code I mean) to the main program. Is it possible to implement in GAMS the same as what we can do in MATLAB?
I would be grateful if you could elaborate it by giving an example.
I'll try to prepare an example in the next week, if I can find some spare time. Anyway, we need, at first, to clarify the meaning of "function" in GAMS, because its language doesn't have function declaration. If you mean a piece of static code, the easiest way is to include it:
$INCLUDE "myfile.gms"
Pls, post what's your problem.
Dear Professor Moriggia,
I am really grateful to you for your worthwhile answer to my question.
Actually, I am going to use an external GAMS program in my main GAMS code. For example, I have a matrix (e.g. Ybus matrix) in my main program but I want to call a Determinant function using "$include determinant.gms" (as you mentioned) in order to calculate the determinant of Ybus matrix.
Is it possible?
I am looking forward to hearing from you soon.
Regards,

Yes, no problem. Just use the same name (Ybus) for your matrix (table or parameter in GAMS language). All you include can be viewed as a script file of MATLAB, i.e. the "workspace" is the same. Input and output variable of included part are visible in the main code.
Hope everything is clear, otherwise do not hesitate to contact me again.
Good luck
Vittorio
