> the UUID consists of a timestamp part and a machine specific part, Not necessarily. There are several formats of UUID.

Otherwise the UUIDs will not be unique accross different LPARs on the same machine. To build UUIDs like this, you need some callable service (I don't recall the name, maybe CSRSI). I wrote a C solution to do this in 2007 ca. for a customer of mine; don't know if I will recall the details. If you want, you can write me offline mail to discuss this (including the communication with COBOL), Kind regards Bernd Am 31.10.2019 um 22:16 schrieb Charles Mills: > Are you up for building a C++ program that you could call from COBOL? > > https://github.com/graeme-hill/crossguid/blob/master/src/guid.cpp > > (Around line 160 there is a bunch of code that is ASCII-specific and not > commented as such.
