Pointer Variables
A pointer variable references an object in the same way as in Pascal—the name of the pointer is followed by a caret (^):
pointer_name^
Any further referencing required to fully qualify an object, such as a member of a pointed-to record, follows the usual Pascal syntax.
Syntax Notes:
1. The final object denoted by the pointer reference must be a scalar value (integer, floating-point or character string). There can be any combination of arrays, records or pointer variables, as long as the last object referenced has a scalar valuThe pointer reference is also used with file type variables.
In the following example, a pointer to an employee record is used to load a linked list of values into the Employee database table:
## type
## EmpLink = ^EmployeeRec;
## EmployeeRec = record
## ename: packed array [1..20] of Char;
## eage: Integer;
## eidno: Integer;
## enext: EmpLink;
## end;
## elist: EmpLink;
...
while (elist <> nil) do
begin
## repeat append to employee
## (name = @elist^.ename, age = @elist^.eage,
## idno = @elist^.eidno)
elist := elist^.enext;
end;
