MVS operating system not available as a selection in the Sterling Connect:Direct Windows Netmap..
No MVS operating system available to select in Remote node Netmap entry
The name under parameter RemoteOSEnv for remote z/OS nodes was changed from MVS to OS/390.
MVS was used for Connect:Direct MVS versions up to 3.2.00.
As these versions are now sunset, the value MVS for selection has been removed.
