The possible flags, their values and their meanings are:
Flags Values Description
------------------------------------------------------
call_type prolog, predicate source
external language
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
deprecated on, off predicate is deprecated,
warning on use
leash stop, see below
print,
notrace
mode pred(Mode1, the mode of the
...) predicate
parallel on, off clauses may be exe-
cuted in parallel
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, is the procedure
dynamic dynamic?
tool on, off tool property
type built-in, type of predicate
user
visibility local, module scope
exported,
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 file
