Re: CA-DUO [EXTERNAL]
Yes it was the UCC days. Like others have said. Was a way to run DOS programs under MVS with out many changes. As others have said a company I worked for used as part of a DOS to MVS migration. That was a long time ago.

It used SVC intercept to make it all work. Last time I used it, was 1981, if I remember correctly, for a restaurant chain that had been trying to migrate from DOS to MVS. So part of their payroll was running under DOS, another part was under DUO (-360), and the rest was native MVS. I can't remember if that was about the time of UCC-2 or before. Definitely before CA. Anyhow, I don't know if CA kept the product up or not. I'm suspecting they didn't. Regards, Steve Thompson On 3/29/22 14:21, Carl Edwards wrote: > Anyone know anything about CA-DUO?

Is there even a need for it anymore. DOS under OS?
