Common Prolog provides a translator from Edinburgh syntax to allow users to port pre-existing code. c onsult and reconsult behave as expected while compile- and-reconsult compiles a file and reconsults the result. Loading of a compiled file is equivalent to reconsult . Edinburgh syntax may also be used to interact with Common Prolog through the use of a different read-query-print loop. To use Edinburgh syntax, use (erqp) instead of (rqp) to start your command loop.
