5.2 Miscellaneous Types
- Pascal space type. This is documented by IBM; what does it mean?
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 -.
- A volatile-qualified version of type-information. This is
a Sun extension. References and stores to a variable with a
volatile-qualified type must not be optimized or cached; they
must occur as the user specifies them.
- File of type type-information. As far as I know this is only used
- A const-qualified version of type-information. This is a Sun
extension. A variable with a const-qualified type cannot be modified.
- Multiple instance type. The type seems to composed of length
repetitions of type-information, for example
character*3is 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.
- Pascal set type. type-information must be a small type such as an
enumeration or a subrange, and the type is a bitmask whose length is
specified by the number of elements in type-information.
In CHILL, if it is a bitstring instead of a set, also use the S type attribute (see String Field).
- Pointer to type-information.
