     2 ERRATA in the book "Isabelle: A Generic Theorem Prover"

     5 Some of these errors are typographical but most of them are due to continuing
     6 changes to Isabelle.

    11 INTRODUCTION TO ISABELLE
    12 
    13 Advanced Methods
    14 
    15 page 52, middle: the declaration "types bool,nat" should be "types bool nat"
    16 
    17 page 57, bottom: should be addsimps in 
    18 	val add_ss = FOL_ss addrews [add_0, add_Suc]

    21 ISABELLE REFERENCE MANUAL
    22 
    23 Introduction
    24 
    25 page 67: show_brackets is another flag, controlling display of bracketting
    26 
    27 Tactics
    28 
    29 page 85: subgoals_tac is another tactic, for multiple calls to subgoal_tac
    30 
    31 Theories
    32 
    33 page 117: the three lines of ML shown can be abbreviated to just
    34 	init_thy_reader();
    35 
    36 page 118: extend_theory has been replaced by numerous functions for adding
    37 types, constants, axioms, etc.
    38 
    39 Defining Logics
    40 
    41 
    42 
    43 page 127: type constraints ("::") now have a very low priority of 4.
    44 As in ML, they must usually be enclosed in paretheses.
    45 
    46 Syntax Transformations
    47 
    48 page 145, line -5: delete repeated "the" in "before the the .thy file"
    49 
    50 Simplification
    51 
    52 page 157 display: Union operator is too big
    53 
    54 page 158, "!": Isabelle now permits more general left-hand sides, so called
    55 higher-order patterns.
    56 
    57 Classical reasoner
    58 
    59 page 176: The package also provides tactics slow_tac, slow_best_tac, depth_tac
    60 and deepen_tac. 
    61 
    62 ISABELLE'S OBJECT-LOGICS
    63 
    64 First-Order Logic
    65 
    66 pages 191, 196: FOL_dup_cs is now deleted (use deepen_tac FOL_cs instead)
    67 
    68 Zermelo-Fraenkel Set Theory
    69 
    70 page 204: type i has class term, not (just) logic
    71 
    72 page 209: axioms have been renamed:
    73 	union_iff is now Union_iff
    74 	power_set is now Pow_iff
    75 
    76 page 215, bottom of figure 17.10: DiffD2 is now  "c : A - B ==> c ~: B"
    77 
    78 page 215, bottom: rules mem_anti_sym and mem_anti_refl are now mem_asym and
    79 mem_irrefl
    80 
    81 page 222, top: missing braces in qconverse_def (around right-hand side)
    82 and QSigma_def (around <x;y>)
    83 
    84 page 223, top: lfp_def, gfp_def have missing braces around the argument of
    85 Inter, Union
    86 
    87 page 228: now there is also a theory of cardinal numbers and some
    88 developments involving the Axiom of Choice.
    89 
    90 page 229: now there is another examples directory, IMP (a semantics
    91 equivalence proof for an imperative language)
    92 
    93 Higher-Order Logic
    94 
    95 page 243: Pow is a new constant of type 'a set => 'a set set
    96 
    97 page 246: Pow is defined by   Pow(A) == {B. B <= A}
    98 empty_def should be  {} == {x.False}
    99 
   100 page 248: Pow has the rules
   101 	PowI     A<=B ==> A: Pow(B)
   102 	PowD     A: Pow(B) ==> A<=B
   103 
   104 page 251: split now has type [['a,'b] => 'c, 'a * 'b] => 'c
   105 Definition modified accordingly
   106 
   107 page 252: sum_case now has type ['a=>'c,'b=>'c, 'a+'b] =>'c
   108 Definition and rules modified accordingly
   109 
   110 page 252: HOL_dup_cs is now deleted (use deepen_tac HOL_cs instead)
   111 
   112 page 254: nat_case now has type ['a, nat=>'a, nat] =>'a
   113 Definition modified accordingly
   114 
   115 page 256,258: list_case now takes the list as its last argument, not the
   116 first.
   117 
   118 page 259: HOL theory files may now include datatype declarations, primitive
   119 recursive function definitions, and (co)inductive definitions.  (These new
   120 sections are available separately as the file ml/HOL-extensions.dvi.gz,
   121 host ftp.cl.cam.ac.uk.)
   122 
   123 page 259: now there is another examples directory, IMP (a semantics
   124 equivalence proof for an imperative language)
