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.

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.

CEERAN0 and Cobol FUNCTION RANDOM both give sets w/30+% duplicates. I have seen website random.org. Anyone have to ever done this thing?
