What is the best way to declare field length 500 in internal table?

Question

Hi all,
what is the best way to declare field length 500(constant value allways) in internal table?
I am trying to send data from internal table to file format, and I have a field in internal table with 500 length (constant value always). So how do I can declare and append this field value to table?
Thanks

Hi.  Please see the following example program, notice how I am filling the field with the constant value.
report zrich_0001.
*       CLASS lcl_main DEFINITION
class lcl_main definition.
  public section.
    types: begin of ttab,
            fld1(500) type c,
           end of ttab.
    data: itab type table of ttab.
    data: xtab type ttab.
    methods: constructor,
             write_itab.
endclass.
*       CLASS lcl_main IMPLEMENTATION
class lcl_main implementation.
  method constructor.
<b>
    xtab-fld1 =
      'This is one part of the total string which needs to be really' &
      ' long and this is a constant and we need to move it to a work' &
         ' area and then append it to the internal table which has a' &
          ' field with a length of five hundred characters'.
    append xtab to itab.</b>
  endmethod.
  method write_itab.
    loop at itab into xtab.
      write:/ xtab-fld1.
    endloop.
  endmethod.
endclass.
data: o_main type ref to lcl_main.
start-of-selection.
  create object o_main.
  call method o_main->write_itab.
