	Adrian,

	I can. But I don't have time to write some examples (and process to 
build external libraries today). I shall try to write these examples as 
soon as possible. In a first time, you can see src/rplexternals.h and 
physical.rplc (in examples/external.tar.gz).

	You can build physical.rplso by mkrplso. External functions can be 
evaluated by :

#!/usr/local/bin/rpl -sc

ESSAI

     "./physical.rplso" use // load external functions

         externals disp // display external functions
         1 energy disp
         1 physical$energy disp
         LIB
     >>

	Name of external functions:
library_name$function_name or function_name if it's name is not ambiguous.
