    Parameter            Definition

    MIB-source-file      A comma-separated list of MIB definition
                         files. The standard extension is .MY, but
                         you can specify any valid OpenVMS file name.
                         You must specify the full file name.

    subtree              The text name for the root of your MIB
                         definitions. This parameter must be enclosed
                         in quotation marks. This name is used in
                         generating names for template C modules and
                         also for the names of the files themselves:
                         subtree_tbl.c and subtree_tbl.h.
