Datatype

Values
|
The type should indicate the intended function of the
pointer, or the rhetorical relationship between its source and
target.
|
|
evaluate |
specifies the intended meaning when the target of a
pointer is itself a pointer.
Status
|
Optional |
Legal values are: |
- all
- if the element pointed to is itself a pointer, then
the target of that pointer will be taken, and so on, until
an element is found which is not a pointer.
- one
- if the element pointed to is itself a pointer, then
its target (whether a pointer or not) is taken as the target
of this pointer.
- none
- no further evaluation of targets is carried out
beyond that needed to find the element specified in the
pointer's target.

Note |
If no value is given, the application program is
responsible for deciding (possibly on the basis of user
input) how far to trace a chain of pointers.
