Hi all, I am trying to write a simple CAS program, to get my feet wet and eventually write a fairly complicated Laplace transform/ matrix / resolvent thing.

My program is:

#cas

QQQ(A):=

BEGIN

RETURN CAS.factor(A);

END

#end

In the CAS screen, when I enter "QQQ(x^2-1)" it yields "factor(A)" but I want "(x-1)*(x+1)"

Could someone tell me what I am doing wrong, and maybe guide me to some documentation? I really have tried googling and RTFMing, but I have no idea.[/font]

Thanks!
