Input Parameters

Parameter Description
HostIdIn Logical ID of a host (or client) with sessions logged on.
SessionNoIn Number of the specified session.
NewAcctString Account string for the session or request.
EntireSession Indicator of how the new account or priority affects requests for a specified session.

If you specify Y or y, the change applies to all current and future requests for a specified session. If no requests or steps are executing, the new account or priority takes effect at the next request, and the DBC.SessionTbl table reflects the new account or priority for the current session.

If you specify NULL, blank, N, or n, the change applies only to the current request for the specified session. If no request is executing, the next request for the specified session has the old account/priority.
