True Random

Odd that it should work like that. It seems as though if the seed wasn't
changed the result shouldn't either.
Thanks!!

Try this:
random/seed checksum form now/precise

you can even use checksum/secure ....

I *think* what is happening is that /Seed and /Secure refinements are in
effect mutually exclusive options. I start random sequences simply by doing
(say)
Random/secure 100
the 100 here isn't a seed it's the range (maximum value of the result). If
I'd written:
Random/seed 100
Then I get no value returned, but a seed value is set internally.
The on line help on random is obscure as it does not distinguish the two
possible meanings of the number
As far as I can tell there is no need to (or point in) setting a seed when
using /secure. But don't take that as definitive: the Core 2.5 manual fails
to mention Random/secure

Hi,
I need to obtane any kind of random in my script, but so far I get the same results although
I try the /seed option. I must be doing something wrong:
append rnd-item random/only/seed [10 24 76 19 20 99 82 73 23 88 77 55 11 28] now/time
lst1-rnd: random/only/seed pplBlock rejoin [now/time]
lst2-rnd: random/only/seed lst2/data rejoin [now/time rnd-item]
append gen-ppl/data rejoin [lst1-rnd "->" lst2-rnd]
remove find lst2/lines lst2-rnd
remove find pplBlock lst1-rnd
Thanks!!

Hi Ammon,
Seed resets the sequence, so you can produce the same "random" numbers over
and over.
Use Secure. Compare these results:
>> random/seed 100
>> random 100
== 41
>> random 100
== 31
>> random 100
== 46
>> random/seed 100
>> random 100
== 41 ;;; sequence repeats
>> random 100
== 31
>> random 100
== 46
>> random/secure 100
== 88 ;; no obvious repeating sequence
>> random/secure 100
== 69
>> random/secure 100
== 17

At the start use:
random/seed now
then just use random/only etc.
