Question: Extract data out of dsolve

Hi,

I am solving a system of differential equations with 2 variables. I can find numerical solution using dsolve with numeric option. I can also plot curves. But I also would like to extract data at time t0 and store into a file. I don't know how to extract numerical values from dsolve and store into a text file at various time, t0, t1, t2 etc. I would like to store data in tabular format with first, sceond and third columns are time, x and y respectively.

 

Just as an example, we can use

x'(t) = y(t), 

y'(t) = 6x(t) - y(t)

with x(0)=1 and y(0) = 2

 

Thanks.
