Re: picking a new random seed

Charles,
Simply constructing an integer from the system clock to use as the
seed {quadRL} for the random number generator may give a less than
ideal sequence.

James J. Weinkam discusses this in this comp.lang.apl group under
"Random Number Generation in IP Sharp APL" (29 Jun 2006 1917)
http://groups.google.com/group/comp.lang.apl/browse_frm/thread/33c60db360b2c7e4/37a0ef84292e7b45?lnk=gst&q=seed#37a0ef84292e7b45

Among the consequences of a poor choice of seed:
"Moreover choosing a seed which is nor relatively prime to the modulus
causes the generator to produce a subsequence which is not of maximum
length."

One recommendation he makes:
"...saving the value of the seed at the end or each run and using that
value to seed the generator at the start of the next run."

I imagine you know this and have a function that selects only "valid
values for {quadRL}" from the clock.  Would you share it?

My crude approach is to simply list {quadRL} after every permutation I
generate (often for assigning students to groups in labs).  Next time
I go back to the listing in the session log to start from there.
