Evenly distributed non-reproducible random integer sequence

Is there a class for producing a sequence of evenly distributed non-reproducible random integers? I'm on a 7.00 system.

If looking for FM then 'QF05_RANDOM_INTEGER'

The answer is yes:


  DATA:
    lv_seed TYPE i,
    lo_prng TYPE REF TO cl_abap_random_int,
    lv_rnd TYPE i.

  " Get a random seed to make the sequence non-reproducible
  lv_seed = cl_abap_random=>seed( ).

  " compute evenly distributed pseudo random numbers in the interval [0,100]
  lo_prng = cl_abap_random_int=>create( seed = lv_seed min = 0 max = 100 ).

  DO c_limit TIMES.

    lv_rnd  = lo_prng->get_next( ).

    WRITE: / lv_rnd.

  ENDDO.
