BitStr DEFINITIONS ::=
BEGIN
-- F.2.5.1
-- Use a bit string type to model binary data whose format and
-- length are unspecified,
-- or specified elsewhere, and whose length in bits is not necessarily
-- a multiple of eight.
-- EXAMPLE
G3FacsimilePage ::= BIT STRING
-- a sequence of bits conforming to Recommendation T.4.
image G3FacsimilePage ::= '100110100100001110110'B
trailer BIT STRING ::= '0123456789ABCDEF'H
body1 G3FacsimilePage ::= '1101'B
body2 G3FacsimilePage ::= '1101000'B
-- F.2.5.2
-- Use a bit string type with a size constraint to model the
-- values of a fixed sized bit field.
-- EXAMPLE
BitField ::= BIT STRING (SIZE (12))
map1 BitField ::= '100110100100'B
map2 BitField ::= '9A4'H
map3 BitField ::= '1001101001'B -- Illegal - violates size constraint
-- F.2.5.3
-- Use a bit string type to model the values of a bit map, an
-- ordered collection of logical variables
-- indicating whether a particular condition holds for each of a
-- correspondingly ordered collection of objects.
DaysOfTheWeek ::= BIT STRING {
sunday(0), monday (1), tuesday(2),
wednesday(3), thursday(4), friday(5),
saturday(6) } (SIZE (0..7))
sunnyDaysLastWeek1 DaysOfTheWeek ::= {sunday, monday, wednesday}
sunnyDaysLastWeek2 DaysOfTheWeek ::= '1101'B
sunnyDaysLastWeek3 DaysOfTheWeek ::= '1101000'B
sunnyDaysLastWeek4 DaysOfTheWeek ::= '11010000'B -- Illegal - violates size constraint
-- F.2.5.5
-- Use a bit string type with named bits to model the values of a
-- collection of related logical variables.
-- EXAMPLE
PersonalStatus ::= BIT STRING
{married(0), employed(1), veteran(2), collegeGraduate(3)}
billClinton PersonalStatus ::= {married, employed, collegeGraduate}
hillaryClinton PersonalStatus ::= '110100'B
