thx John and Steve... I hadn't understood until now the difference between the Co:Z Launcher and the Co:Z Batch products. I agree, it could be interesting to use the Launcher within as well as between hosts. The graduation of usage of Java that you describe below is succinct and new to me.
Someone else told me offline that Dovetail was the creator of the IBM JZOS product as well -- good work. I'll drop by the Co:Z forum if I have more questions... cheers Peter Bishop On Thu, 21 Jun 2012 07:47:28 -0500, McKown, John <[email protected]> wrote: >JZOS is designed to run Java programs in batch.
