Need suggestion about long matrix program

[rawi]

Hi Amer,
matrices M0 to M9 always are not local to a program (its the same with lists L0 to L9). That is you just put them in the computer outside of the program, you use them in the program as defined variables without defining them in the program, you modify them in the program and after the program ends you will have them as results and can look on them. So I think this is rather convenient.
I used this extensively for instance in the following thread:
