In an environment where TP1/Server does not exist, you can communicate with a DCCM3 logical terminal or another server by specifying DCCLTNOSERVER=Y in the client environment definition.

You must issue the dc_clt_cltin_s function even when communicating with a server other than TP1/Server. In the logname argument of the dc_clt_cltin_s function, specify a value other than NULL. If you specify NULL, the dc_clt_cltin_s function will return with the DCCLTER_INVALID_ARGS error.
