I like the idea of going to share but 'NO CHANCE' Thanks for the offer of talking directly but I really just need to make sure I am NOT heading for a big fall. I don't think I am but just wanted to know if I had missed something that might come and bite me later.

But not so different. Especially on System z and current version of z/VM. Rather than type long winded messages, I can set up a call.

Query: why under z/VM??
