Pointer Reference

An example of a pointer declaration is: 


   var p: ^person

Note that the POINTERSYM record points to the name of the record rather than to the RECORDSYM entry.

A pointer reference such as: 


   p^.friend
is handled like an array reference, with the pointer reference in the base address location: 

   (aref (^ p) 4)
where we assume that 4 is the offset of the friend field from the start of the person record.

The file pasrec.sample contains examples of code that is compiled for pointer references.
