DSNL019I VTAM DOES NOT SUPPORT APPC FUNCTIONS

Explanation
 The installed release of VTAM® does not support the advanced program-to-program
communications (APPC) application program interface (API). The APPC
API bit is not set in the VTAM function-list
vector in the access-method-support vector list.

System action
 Termination of the distributed data facility
(DDF) is initiated.

Operator response
 Notify the system programmer.

System programmer response
 Determine whether the installed release
of VTAM supports the APPC API.
If VTAM does not support the
APPC API, a VTAM release that
supports the APPC API must be installed before the DDF can be started.
