Pointers and references: Difference between revisions

Phix does not have pointers, other than for playing with raw allocated memory, typically for interfacing with another language pre-compiled into a dll/so, although for that builtins/cffi.e offers a more grown-up mechanism with seamless 32/64 bit portability. There is no pointer math beyond sizes in bytes.
