Re: external data structure in free rpgle cant be use in DCL-PI ?

Yes, it's an unusual shorthand syntax.

  dcl-s myVariable char(100) based(pVariable);

This automatically defines a pointer variable named pVariable.  As I said, it's a bit unusual.  It's the same as this:

  dcl-s myVariable char(100) based(pVariable);
  dcl-s pVariable pointer;

You just don't need to do the second declare.

Using the old *Entry Plist approach what actually happened was that the

DS declared as the parm was (under the covers) declared as BASED by the
compiler and the pointer passed for the parm just assigned as its basing
pointer. All that the pointerToDS = %addr(parmname); code is doing is the
same thing that used to happen under the covers.

Quite why the compiler made this change is a mystery to me - I don't

recall any discussions on the topic - and it may be something that can be
changed in the future.

What change do you mean, Jon?
