Hi Igor,

You can run eclipse with the -b and -e command line options
http://eclipse-clp.org/doc/userman/umsroot152.html, e.g.

eclipse -b my_code.ecl -e "my_top_predicate(args)"

If you are on Windows, the executable is at
%PROGRAMFILES%\ECLiPSe 6.0\lib\i386_nt\eclipse.exe

Depending on what is more convenient to do from your host program,
the eclipse code could read its input data either from the standard
input stream and write its results to standard output, or use
files, or sockets.
