The whole system is not easy to manage. At least to me far from being intuitive. Personally I solved my problem with a cas-function that was called by the input function, but I disliked that. I will try to understand cyrille's paper and the proposed code.
Frustrating thing ;-)

Well, there is one more piece to be taken at some point (hopefully in the not too distant future) - the ability to declare a variable as a symbolic identifier. That should be the last step to allowing clean access to the CAS. Something like this is kind of the direction I'm thinking.

LOCAL x:=id(x); //or possibly LOCAL x=id('x');
x=CAS.int(x^2-2,x);
print(x);
return x;

or similar would then work like you'd think.

Should look familiar to anyone who's used SymPy I'd think.


What really happened in this last release is that using local variables for function calls behaves in a consistent manner rather then automatically replacing the variables with content on evaluation. The limitation of "the variable still contains some content - even if it is 0" is still there.

Hence the thinking for the future improvement I mused about above.

Although I work for HP, the views and opinions I post here are my own.
