We have been using VTAM/SWITCH from MacKinney Systems for over 20 years. We use the VM version that is no longer supported but it works so we're sticking with it. It runs in GCS.
Users can access multiple sessions on VM or VSE. I believe if you used the VSE version that you could still access VM if you have VM/VTAM. The price was quite reasonable as all MacKinney products are. /Fran Hensler at Slippery Rock University of Pennsylvania USA for 46 years mailto:f...@zvm.sru.edu http://zvm.sru.edu/~fjh +1.724.738.2153 "Yes, Virginia, there is a Slippery Rock" --------------------------------------------------------------------------
