thanks very much,
Alejandro.
or maybe someone knows where could I download a AFX2.0 laplace transforms program?????

Tryig to create algebraic evaluation of expression in Casio Basic is just utter nonsense

at least on the AFX.If the program relies on symbolic manipuliation, porting it is most probably not possible.

But if someone has too much free time then nothing is impossible

Certain things are not within the scope of the hardware..But if someone has too much free time then nothing is impossible
Emulating things you would usually do in machine language (like symbolic manipulation) in Basic, would not only grind to a halt, it would probably be impossible to implement due to memory constraints on the AFX.

limit exp(x) when x tends to -ve infinity (answer is zero), then yes, it does it in the CAS mode!
I have promised epaloco to tell him how to do Laplace on the AFX step-by-step (not by programming) if he sent me the TI-89 code, but I don't understand it all well.
So, Aleph, if you could just translate the code here to mathematical steps, that would be great!
