DSNT456I ERROR IN VARIABLE varname, VALUE IS value

Explanation
 The variable named 'varname' does not have a valid
value. Its current value is 'value'. Subsequent messages will describe
the reason the value is invalid and the action taken by the CLIST.
 If
the error is in the CONTROL value, the value was specified when the
CLIST was invoked. The value is not valid, and no additional tracing
will be done. The permitted values are  NONE, LIST, CONLIST, and SYMLIST.
Each value produces more CLIST tracing information than those which
precede it. If the error is in other values, the value was specified
when the CLIST was invoked on the ISPF panels.
 This message
is issued by the following installation CLIST: DSNTINST

System action
 The CLIST will continue, but will not produce
jobs or parameter data.

User response
 Check the subsequent messages. Exit, then invoke
the CLIST with a valid value for the variable.

Problem determination
 If you suspect an error in the process,
set CONTROL(CONLIST) and invoke the CLIST in batch, so that the tracing
can be sent with the error documentation. The CLIST itself and the
parameter member read in should be sent as well.

Severity
   8 (error)
