Re: Learning RPG IV advanced techniques

My favorite language is probably still EDL for the Series/1.  If you changed *-2, you were actually changing the PROGRAM CODE.  That's how we did poor man's recursion.  Ah, those were the days.

I have been corrected. Pascal and Modula 2 do support pointers. They are

The same is true of PL/I pointers. And of course, pointers in (LISP).

Pointers originated in PL/I. Not only did PL/I (1964) predate C (1972); it also predated B (1969) and BCPL (1967).
