programs disappearing from toolbox menu

[Tim Wessman]

Hello,

It is actually a completely consistent design.

The issue is that the cas does not have the concept of a program source file. You cannot have a file that contains a bunch of related functions, variables, and so on. Additionally, every thing from the cas perspective is a variable containing an object. In this case, you have a variable containing a function definition.

It truly is a variable. You can delete it, store into it, and do everything you'd expect from any other variable.

The purpose of the #cas directive is to throw the compiler into a mode where it begins executing your lines as if you were typing them on the cas screen. This does not mean your functions are protected from deletion, or having the user override them. They are just variables stored into the cas memory.
