parameter a file name to be saved

[Daniel Tourde]

Hello,

I would like to know if it is possible to parameter files name and files
locations.

I have a function f(a) which produce a matrix function of a. I would
like to save it in a dircetory called ~/dir_a with the name a.dat. 
So if a = 1, I would like to have ~/dir_1/1.dat
   if a = 2, ~/dir_2/2.dat ...

Does anyone know if it possible and then how to do it.

Thanks in advance

                        Daniel
