-- This module exercises snacc's semantic error checking of ASN.1 types.
-- Every line that has the "error" comment should cause snacc to produce
-- at least one error message

ERROR-TEST DEFINITIONS ::=
BEGIN


-- first check that CHOICEs and SETs  without distinct tags
-- cause error msgs

AChoice ::= CHOICE -- error
{
    f1 [0] INTEGER,  -- these two have the same
    f2 [0] INTEGER,  -- tags
    f3 INTEGER,      -- the tag of f3
    f4 AChoice3      -- conflicts with one of AChoice3's elmt tags
}

ASet ::= SET  -- error
{
    f1 [0] INTEGER, -- same [0] tags
    f2 [0] INTEGER

T1 ::= INTEGER
T2 ::= BOOLEAN

AChoice2 ::= CHOICE  -- error
{
   T1,
   INTEGER
}

ASet2 ::= SET  -- error
{
   T2,
   BOOLEAN
}

AChoice3 ::= CHOICE

--
-- now check that Sequence have distinct tags
-- on one or consective optional elmts and following (if any)
-- non-optional elmt

--
-- now check that duplicate APPLICATION tag errors are reported
--
Foo1 ::= [APPLICATION 0] INTEGER
Foo2 ::= [APPLICATION 1] INTEGER

Bar1 ::= [APPLICATION 0] IMPLICIT INTEGER  -- error

--
-- check that field name errors are reported

     INTEGER,
     BOOLEAN,
     RecSeq,  -- warning, infinitely large values?
     RecSeq OPTIONAL -- this should be ok 'cause it's optional

--
-- now check some named bit and named number related errors
--
aVal  INTEGER ::= -4

Enum1 ::= ENUMERATED { zero(0), one(1), two(2), one(0) } -- 2 errors

Int1 ::= INTEGER { zero(0), one(1), two(2), yoyo(2), one(7), foo(aVal) } -- 2 errors

Bits1 ::= BIT STRING { zero(0), one(1), two(2), one(4), foo(-2), pogo(0),
                       gogo(aVal) }  -- 4 errors



--
-- now check that implicitly tagged CHOICE, ANY and ANY DEFINED BY
-- cause error msgs
--
BChoice1 ::= [APPLICATION 5] IMPLICIT CHOICE  -- error
{
    INTEGER,
    BOOLEAN
}

BChoice2 ::= CHOICE -- no error
