“VPSET PTV ON” Command – Support Discontinuance

Please be advised the support for “VPSET PTV ON” command has changed.


For more than the past decade, attempted use of the VPSET PTV ON command has issued the following message:

Because IBM has withdrawn PTV mode from z/TPF, VSSI plans to remove PTV support from VPARS.

If you still have a use for VPARS PTV mode, please notify VSSI support.

Given we have not heard from any customers still using PTV mode for several years now, effective immediately, VSSI will remove PTV support as encountered in the code during regular update activity.
