If you specify location, which is either a z/OS® UNIX file or a sequential file (or PDS member), with the TEMPLATEREGISTRY compile option, the compiler writes the template registry to that location. If you do not specify location with the TEMPLATEREGISTRY option, the compiler determines a default destination for the template registry file. See TEMPLATEREGISTRY | NOTEMPLATEREGISTRY (C++ only) for more information on this default.
If you specify location, which is either a z/OS UNIX directory or a PDS, with the TEMPINC compile option, the compiler writes the template instantiation output to that location. If you do not specify location with the TEMPINC option, the compiler stores the TEMPINC output in the file that is associated with the TEMPINC DD name. If you did not allocate DD:TEMPINC, the compiler determines a default destination for the template instantiation files. See TEMPINC | NOTEMPINC (C++ only) for more information on this default.
