To compile a program into bytecode use:

gen file

where file is the prolog source file.  Several sample programs exist in
directory "rolog_progs" at the same level as "gen".

Two files, Bytecode and Bytecode.pure, are created in the current directory.
The first contains bytecode and the second purecode.  The utility "disasm"
produces an annotated disassembly from these two files.  The binary for disasm
is in rolog_compiler/gen/list/disasm, and there are symbolic links to it 
from various convenient places.

if you type 

gen -o <outfile> file

then the two files created are named <outfile>.bc and <outfile>.pure 
respectively.
