+\S{rdfimpt} \c{rdf} Extensions to the \c{EXTERN} directive\I{EXTERN,
+rdf extensions to}
+
+By default the \c{EXTERN} directive in \c{RDOFF} declares a "pure external" 
+symbol (i.e. the static linker will complain if such a symbol is not resolved).
+To declare an "imported" symbol, which must be resolved later during a dynamic
+linking phase, \c{RDOFF} offers an additional \c{import} modifier. As in
+\c{GLOBAL}, you can also specify whether an imported symbol is a procedure
+(function) or data object. For example:
+
+\c     library $libc
+\c     extern  _open:import
+\c     extern  _printf:import proc
+\c     extern  _errno:import data
+
+Here the directive \c{LIBRARY} is also included, which gives the dynamic linker
+a hint as to where to find requested symbols.
