Miscellaneous Types

b type-information ; bytes

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 section Defining Builtin Types Using Builtin Type Descriptors) because the character following the type descriptor is always a digit, `(', or `-'.

B type-information

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.

d type-information

File of type type-information. As far as I know this is only used by Pascal.

k type-information

A const-qualified version of type-information. This is a Sun extension. A variable with a const-qualified type cannot be modified.

M type-information ; length

Multiple instance type. The type seems to composed of length repetitions of type-information, for example character*3 is represented by `M-2;3', where `-2' is a reference to a character type (see section 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 section Subrange Types.

S type-information

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 section The String Field).

* type-information

Pointer to type-information.
