SELF_LOOP

    Number of self-iteration loops. It is a ReadOnly variable that is  automati-
    cally  computed from the size of the SELF_TIMES, SELF_NITER and SELF_MINFLUX
    arrays.

      These variable length arrays can be resized using the LET /RESIZE command.
    For example
        LET SELF_TIMES 40 20 10 /RESIZE
    will lead to an array of 3 elements, SELF_TIMES[3].

    SELF_TIMES, SELF_NITER and SELF_MINFLUX must be of equal size.  To  simplify
    the  process, constant arrays are assumed of arbitrary length in this deter-
    mination.  If all 3 arrays have constant values, SELF_TIMES  determines  the
    number of loops.

    Constant  arrays  are  assumed of arbitrary length in this determination. If
    all 3 arrays have constant  values,  SELF_TIMES  determines  the  number  of
    loops.
