I want to retrieve data from google finance to do some analysis. Since the amount of data pieces are very huge. To aviod a huge amount of copy and past operations, I need to do it automatically in maple. So my question is how can I reduce the work in Maple as much as possible? I know google offers some APIs for retrieving data. Can I utilize that in Maple?

I want to get the length of a list. Is there any command available for that? For example, I want it return 2 for the list [8374, 32875], since it has two items.

I have a loop in my program. It sometimes takes a long time to run. I want to output a value of a variable that indicate how many jobs has been done. Since this value changes constantly, so the ordinary print method will generate a large amount output. Is there any way I can make this value shows in just one area dynamically?

I knew that fsolve can solve equations by given an interval or a starting point. Like these

fsolve({x-y = 1, x+y = 1}, {x = 0 .. 1, y = 0 .. 1})

fsolve({x-y = 1, x+y = 1}, {x = 0, y = 1})

But what if I knew the interval for only one of the the variable?  After I run this code

I'm using fsolve to solve a system of two equations with two unknown variables. Like this,

fsolve({u(b) = z(b-a), u(a) = Zeta1(a-b)}, {a = -.2, b = .2}).

As we know, the solution shows like this:

{b = .2189682330, a = -.1937146254}
