Random/seed
[1/5] from: robert::lancaster::opennw::com at: 18-Apr-2001 9:09
Hello All...
random/seed 1 while [ 1 ] [ print random 100 ] ; on a Win
98 box....
Always produces an identical list of random numbers everytime it's run.
Can this be relied on to produce the same identical list of random numbers,
each time it is run on varying platforms?
I have to ask because I only have access to one type of platform.
Thanks..
p.s Glad to see I can open a UDP listen port under 2.5 now....I had great
trouble with it before... Don't ask me why.. I just did!

I get this set of numbers on my Windows and Linux boxes using PII's. I expect
it might be different on non Intel machines.

Thanks a lot for the help every one.
I was looking at using it to produce a numbering system for a protocol over
UDP. Trying to get a method for working out which packets had gone missing
by their internal data, numbering and/or length.
Realised there's a few holes in my logic. So having a rethink... Might have
to write my own Pseudo Random Number Generator, so I can get random
non-repeating numbers.

If the random number generator avoids direct bit fiddling (or it takes
care of endian issues) and the same implementation is used on every
platform then you will always get the same number sequence for a given
seed regardless of platform.
