About memory issues...

Hi there!
   I'm using the function random_uniform inside a do loop, however
when I execute it a second, third and n - time it always returns the
same values, here it is the script and the results:

;*******************************************************************************************************
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"

begin
do i = 1, 5
X = (/-2.41, 4.86, 6.06, 9.11, 10.2, 12.81, 13.17, 14.1, 15.77, 15.79/)
a = round(random_uniform(0,dimsizes(X)-1,dimsizes(X)),3)
print(a)
delete(a)
end do

end
;********************************************************************************************************

The results are:

And so on...

It seems that the memory allocation is the same, does anybody knows
how to clean this memory allocation from ncl???

Thank you very much
Regards
