Protecting variables/data

LeJonT

Hi,

Is ther any way to protect variables used in a SKILL procedure, so that it doesn't get changed by any other procedure? Making private using let/prog is a get around. Is there any way to do the same for globals too? Like attaching a set of variables to a set of processes, so that only those procedures would be able to change them.

  •  Maybe the documentation helps here "SKILL Language User Guide",

    Chapter 10 "Delivering Products", Section "Protecting Functions and Variables".

  • Also, you might want to take a look at the chapter in the same manual on SKILL++ (two chapters - "About SKILL++ and SKILL" and "Using SKILL++"). This covers how you can create closures and packages to hide functions and variables - essentially make private variables which are shared between several functions in a lexical scope.

    This is the way I tend to do this kind of thing rather than relying on write protection.

    Regards,

    Andrew.
