Hello Jim,
No problem.? I may have been a little harsh with my criticism.? I was also trying to get SPF working around the same time as VTP and there were some issues with that as well so I may be getting the findings from both mixed up.
I had also been running the modified version of the DOS/VS 5 Pack system v1r0m1 at times, so that may have had some bearing.
I should say that I was running DOS/VS native as opposed to under VM/370.
It will be interesting to see how you get on with it and if I find the time, I may re-visit it with a fresh perspective.
All the best,? Alex.
