Sources for External Data Structures

["Roger Vicker, CCP" <rvicker@xxxxxxxxxxxxx>]

Greetings,

I would like to drum up some support for a change in how the RPG
(III/IV/ILE) compilers handle external data structure definitions.
Currently, you can only effectively reference a *PF or *LF. If you
reference a *PRTF it will compile but tell you:

and it will not bring any field definitions (even if your are
referencing them. Ex. INZ) into the program.

The v3r7 CD-ROM does not mention any restrictions on this for ILE.
 
Please let IBM (Hans are you still following the list?) know that RPG
<SHOULD> accept any type of externally described file and pull in the
field definitions. I know this is not a major item but is in the same
line as being to rename fields for an *OUTPUT only file. It would make
some things much easier or clearer.
