multiple arrays

Dear all,

I would like to define a multiple array:

 for m:0 thru 100 step 1 do
    for k:0 thru 100 step 1 do
         for n:0 thru 100 step 1 do
              for l:0 thru 100 step 1 do
                        Character[m][k][n][l]:0;

But it is not correct. How could I define the multiple array
Character[m][k][n][l] in a correct way?
Thank you very much.

Best wishes,
Jianrong.
