How to save a CAS program

[Tim Wessman]

The basic issue boils down to this: CAS programs are not really programs but rather saved function objects. There is no difference between f(x)->x^2 and a much more complicated func()->begin...end that has hundreds of lines.

What this means is that there is no way to save them separately or differently at this point in time. There are several possible solutions/workarounds, but all of them are dependent on some other things that are quite tricky to implement and in order to resolve completely will requires some significant changes/updates.

In short, no matter how big or large the CAS "program", you really should think of them as a function definition and the restrictions/behavior in place currently suddenly makes much more sense.
