DEFAULT

 Overrides certain compiler options that can affect external routine
 and COMMON block declarations.

 It specifies that the compiler should ignore compiler options that
 change the default conventions for external symbol naming and
 argument passing for routines and COMMON blocks (/iface, /names,
 and /assume:underscore).

 This option can be combined with other cDEC$ ATTRIBUTES options,
 such as STDCALL, C, REFERENCE, ALIAS, etc.  to specify attributes
 different from the compiler defaults.

 This option is useful when declaring INTERFACE blocks for external
 routines, since it prevents compiler options from changing calling
 or naming conventions.
