Hi, Can anyone tell me why this function in Mathematica doesn't work? Its supposed to be given a list, and just copy it to another list, and print it:
g = Function[m,
    Module[{i, l},
      i = 1;
      l = {};
      While[i ¡Ü Length[m],
          Append[l, m[]];
          i++
          ]
        Print[l]
      ]
    ]
however, I get {} ... Any help? Thanks

Append doesn't modify lists. It takes a list and an element, then returns the list with the element appended.

thanks... so this is what I did:


g = Function[m,
Module[{i, l},
i = 1;
l = {};
While[i ¡Ü Length[m],
l = Append[l, m[]];
i++
]
Print[l]
]
]


When I run it like this:


g[{1,2,3}]


i get:


{1,2,3}
Out[3]=Null^2


the {1,2,3} is correct, but what is that Null^2 ??


thanks again
