Hi all,

I am looking for a way to generate random numbers with good quality.
The system the generator should be working on is an MVS system.

Does anyone have a clue of how to do it ?

Thanks in advance,

Djeanne.


There's lots of resources on the web:
http://en.wikipedia.org/wiki/Pseudorandom_number_generator

Linear Congruence was described by Donald Knuth over 30 years ago, and would be relatively simple to implement in COBOL. It's fairly good for simulations, not good at all for cryptographic purposes.

You might consider researching RC4 if you need a Pseudo-Random Number generator that has some desireable qualities for cryptography. It can also be implemented in COBOL, with a little work.
