LET /RESIZE

        [SIC\]LET Variable [=] Val1 ... ValN /RESIZE

    Automatically resize the variable according to the number of  values  to
    be stored in the output variable. For example:
        SIC> define integer a[2]
        SIC> let a 1 2 3 /resize
        W-LET,  Resizing array A to length 3
        SIC> exa a
        A               is an integer Array     of dimensions  3
                    1            2            3

    This  feature  makes  sense when the array size is not known at the time
    the procedure in written, but have to be  decided  instead  from  unpre-
    dictable  inputs  at  run  time (e.g. user input in widgets). It applies
    (only) to 1D arrays of any kind (numeric, logical, character). The type,
    kind,  rank and level (global/local) of the output variable is not modi-
    fied during the process. Read-only and program-defined variables can not
    be resized.
