One way

How about this?
>restart:
> LL := [1, 2, 3];

[1, 2, 3]
> b := convert('LL', string);

"LL"
> b;

"LL"
> LL;

[1, 2, 3]

declare parameters as uneval

The following does what you want. The technique is to declare the parameters as ?uneval, and then evaluate them inside the body of the procedure.

f := proc(A::uneval, B::uneval)
local a,b,La,Lb;
    a := convert(A,string);
    b := convert(B,string);
    La := eval(A);
    Lb := eval(B);
    return a = La, b = Lb;
end proc:

A1 := [1,2]:
B1 := [3,4]:

f(A1,B1);
                         "A1" = [1, 2], "B1" = [3, 4]

Thanks

This is what I wanted, however I modified it a bit:

restart:
f := proc(A::uneval, B::uneval)
global a,b,C:
    a := convert(A,string);
    b := convert(B,string);
    C:=A+B;
end proc:
A1 := [1,2]:
B1 := [3,4]:
f(A1,B1):
a;
b;
C;



                                    "A1"
                                    "B1"
                                   [4, 6]
coco:=5:
MyNum:=2:
f(MyNum,coco):
a;
b;
C;
                                   "MyNum"
                                   "coco"
                                      7
