[Scilab-users] Variables visibility in functions

[kjubo]

Dear all,

I would like to ask you, how can I disable visibility of variables from
workspace for functions.

I need to be sure, that function which I convert from script file, will not
use any variable, which is not in it input, or defined inside the function
itself.

Please see examples below.

Is this possible?
        
Thank you

        example 1:

        a = 3
        function fx = some_fun(x,a)
            fx = x+a
        endfunction

        calling some_fun(5) now return 3+5, but I need to be an error.


        example 2:

        a = 3
        function fx = some_fun(x)
            fx = x+a
        endfunction

        I need also error, as variable a should be passed as input argument
or defined inside some_fun body
