DSNT454I ERROR CODE = errcode, CNT = count

Explanation
An error was encountered during CLIST processing for reading the parameter
member. Most of these errors are caused by having a mismatch between the level
of the CLIST and that of the parameter member being read.

The 'errcode' is an error code defined for the CLIST. The error
code values and associated meanings are found in TSO/E CLISTS.

The 'count' value is the number of parameter values already read.

This message is issued by the following installation CLIST: DSNTINST

System action
The CLIST will terminate.

User response
Be sure the parameter member and the CLIST are at the same level.

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.
You will also need the listing of the CLIST and the parameter member being
read.
