Bug? accessing LOCAL var in shared scope

[Dirk.nl]

Hi Marcus,

When I select the catalog in CAS, I see SIN in uppercase. Conclusion, it's a Home function, but maybe yes or no, after selecting it, it will be copied in lowercase to the command line. New conclusion, if you are not be sure if it is also a CAS function, try to copy it to the command line!

I have used length() in a Home program, it was not copied in uppercase, but it works in my program! A lowercase CAS function that works well in a Home program without CAS. before the function!
I think that the difference (maybe not the good word for it) between Home/CAS is not consistent enough. Request to HP; make this more clearer!!
