<P>

The type symbols defined by the system include those shown in
|
||
|
|
table <A HREF="node45.html#TYPESYMBOLSTABLE">4-1</A>.
|
||
|
|
In addition, when a structure type is defined using <tt>defstruct</tt>,
|
||
|
|
the name of the structure type becomes a valid type symbol.

<i>Notice of correction.</i>
|

|
|
<tt>unsigned-byte</tt> were inadvertently omitted from
|

|
|
table <A HREF="node45.html#TYPESYMBOLSTABLE">4-1</A>.

<P>
|

|
|
or of conditions (see chapter <A HREF="node312.html#CONDITION">29</A>).
