Pointers and Compiling Programs for 64-Bit

If you compile a program using the P64 Compiler directive (referred to in the rest of this chapter as "64-bit programs") the data-type POINTER is a different size to that in programs compiled without the P64 directive (referred to in the rest of this section as "32-bit programs").

To help you find invalid manipulations of the data-type POINTER in your programs, use the Scan64 utility.
