Well, this is not an array but i think it may help (or not).
 
        int **array;
        
        array=(int **) firstmem (sizeyouwant_lines * sizeof (char *));
         for (lines=0;lines<sizeyouwant_lines;lines++)
         {
          array[lines] = (char *) malloc(sizeyouwant_rows * sizeof (char));
         };
        

Hope, this help (and works) ehhehe
