REDIM variable-name [ arg-list ] [ , variable-name [ arg-list ] ... ]

   Synopsis:
      Changes the size and dimensions of array variables

   Notes:
      All values already stored in the array are replaced with default values
         (empty strings for string arrays, or zeroes for numeric arrays).
      The expressions in the argument list(s) must evaluate to positive 
         integers.
      Axbasic arrays have a maximum size of 1,000,000 cells.

   Examples:
      ! An array containing 5 cells
      DIM myarray (5)
      ! Store a value in the first cell
      LET myarray (1) = 3.14
      ! Change it to a two-dimensional (10x10) array containing 100 cells
      REDDIM myarray (10, 10)
