b type-information ; bytes
This use of the b type descriptor can be distinguished
from its use for builtin integral types (see Builtin Type Descriptors) because the character following the type descriptor is
always a digit, (, or -.
B type-information
d type-information
k type-information
M type-information ; length
character*3 is
represented by M-2;3, where -2 is a reference to a
character type (see Negative Type Numbers). I'm not sure how this
differs from an array. This appears to be a Fortran feature.
length is a bound, like those in range types; see Subranges.
S type-information
In CHILL, if it is a bitstring instead of a set, also use the S
type attribute (see String Field).
