  22 <dt><code>b </code><var>type-information</var><code> ; </code><var>bytes</var><code></code>
  23      <dd>Pascal space type.  This is documented by IBM; what does it mean?
  24
  25      <p>This use of the <code>b</code> type descriptor can be distinguished
  26 from its use for builtin integral types (see <a href="Builtin-Type-Descriptors.html#Builtin%20Type%20Descriptors">Builtin Type Descriptors</a>) because the character following the type descriptor is
  27 always a digit, <code>(</code>, or <code>-</code>.
  28
  29      <br><dt><code>B </code><var>type-information</var><code></code>
  30      <dd>A volatile-qualified version of <var>type-information</var>.  This is
  31 a Sun extension.  References and stores to a variable with a
  32 volatile-qualified type must not be optimized or cached; they
  33 must occur as the user specifies them.
  34
  35      <br><dt><code>d </code><var>type-information</var><code></code>
  36      <dd>File of type <var>type-information</var>.  As far as I know this is only used
  37 by Pascal.
  38
  39      <br><dt><code>k </code><var>type-information</var><code></code>
  40      <dd>A const-qualified version of <var>type-information</var>.  This is a Sun
  41 extension.  A variable with a const-qualified type cannot be modified.
  42
  43      <br><dt><code>M </code><var>type-information</var><code> ; </code><var>length</var><code></code>
  44      <dd>Multiple instance type.  The type seems to composed of <var>length</var>
  45 repetitions of <var>type-information</var>, for example <code>character*3</code> is
  46 represented by <code>M-2;3</code>, where <code>-2</code> is a reference to a
  47 character type (see <a href="Negative-Type-Numbers.html#Negative%20Type%20Numbers">Negative Type Numbers</a>).  I'm not sure how this
  48 differs from an array.  This appears to be a Fortran feature.
  49 <var>length</var> is a bound, like those in range types; see <a href="Subranges.html#Subranges">Subranges</a>.
  50
  51      <br><dt><code>S </code><var>type-information</var><code></code>
  52      <dd>Pascal set type.  <var>type-information</var> must be a small type such as an
  53 enumeration or a subrange, and the type is a bitmask whose length is
  54 specified by the number of elements in <var>type-information</var>.
  55
  56      <p>In CHILL, if it is a bitstring instead of a set, also use the <code>S</code>
  57 type attribute (see <a href="String-Field.html#String%20Field">String Field</a>).
  58
  59      <br><dt><code>* </code><var>type-information</var><code></code>
  60      <dd>Pointer to <var>type-information</var>.
