Hi Richard,
Paul is right, we came up with the same solution
There are several statistical tests for randomness, perhaps the easiest to
calculate is MSSD (mean squared successive differences) and you are on the
right track
You can attach my name
Melvyn.

Fantastic. This looks to be the level of brilliance I was looking for -
simplicity plus 100% solution.
So follow-up question. I have a lot of advanced math in grad school, all
inapplicable to this. Is there any kind of measure of how "random" a set of
numbers is? Someone internal is bound to ask. I am thinking of graphing
the difference [=n(i+1)-n(i)] and looking at distribution. The client(s)
are business persons and are unlikely to ask.
Question 2: I have a passion for documenting things. Do you wish to have
your name attached to this idea?
Tomorrow when I have time I will peruse all the answers.
Profound thanks
Peace be w/y'all

1. Use either CEERAN0 or FUNCTION RANDOM to generate a column of 99,999
random numbers. It's OK if there are duplicates.
2. Add a second column using SORT with sequential numbers from 1 to 99999
(use the SEQNUM option).
3. SORT by the first column only and DO NOT specify the EQUALS option.
4. Use the numbers in column 2 after sorting as your 99,999 randomly ordered
numbers
You can combine steps 2, 3, and 4 in one SORT execution. INREC to add the
SEQNUM's as a second column, SORT by first column, OUTREC to select only the
second column for output.

So I need a set of 99,999 random numbers which are 5 digits and unique, i.e.
no duplicates. CEERAN0 and Cobol FUNCTION RANDOM both give sets w/30+%
duplicates.
I have seen website random.org.
Anyone have to ever done this thing?
Anyone have suggestions?
