The contents of the ECLiPSe BIP book, i.e. the detailed descriptions of all built-in predicates, can be accessed with the help-facility. It has two modes of operation. First, when a fragment of a built-in name is specified, a list of short descriptions of all built-ins whose name contains the specified string is printed, .e.g.
will print one-line descriptions about write/1, writeclause/2 etc. When a unique specification is given, the full description of the specified built-in is displayed, e.g. in:- help(write).
:- help(write/1).
