unskipped +SpecList

Sets the procedures specified in SpecList to be unskipped or not skipped.
SpecList
Sequence of expressions of the form Atom/Integer.

Description

Undoes the effect of a call to skipped/1 on the specified procedure(s), i.e. its subgoals will now be traced.

The expressions in SpecList are all of the form name/arity.

Note that unskipped/1 is superseded by the predicate set_flag(Proc, skip, off), which sets the procedure Proc to be unskipped.

Modes and Determinism

Modules

This predicate is sensitive to its module context (tool predicate, see @/2).

Exceptions

(4) instantiation fault
SpecList is not instantiated.
(5) type error
SpecList is instantiated, but not of the form atom or Atom/Integer.
(60) referring to an undefined procedure
SpecList contains an undefined procedure.
