The possible flags, their values and their meanings are:
Flags Values Description ---------------------------------------------------------------------- auxiliary on,off predicate is a compiler auxiliary break_lines list of list of predicate source File:Line atom:integer that currently have breakpoints set call_type prolog, predicate calling external convention code_size an integer size of abstract machine code in words (32/64 bits) debugged on, off compiled in debugging mode declared on, off predicate was declared defined on, off predicate code exists definition_module an atom where the procedure is defined demon on, off predicate is a demon deprecated on, off predicate is deprecated, warning on use leash stop,print, see below notrace mode pred(Mode1,...) the mode of the predicate parallel on, off clauses may be executed in parallel port_calls list of list of DefModule:Name/Arity for atom:atom/int the predicate's body goals where breakpoints can be added. The port_lines option returns the source information for these ports, in the same order port_lines list of list of predicate source File:Line atom:integer where breakpoints can be added. The port_calls option returns the goal information for these ports, in the same order priority 1..12 waking priority skip on, off procedure will be traced, but its children will not spy on, off procedure has a spypoint stability static,dynamic is the procedure dynamic? tool on, off tool property type built-in,user type of predicate visibility local,exported module scope reexported, imported source_file an atom the file where defined source_line an integer starting line number in the file source_offset an integer byte offset at which the procedure definition starts in its source fileThe possible values of leash and their meanings are:
