As a stop gap measure, we are using Google's custom search engine service.

Hans,
I think a free-format I/O spec is not necessary. We already have a pretty
good D spec, why not just allow that to be used for (at least) Input specs?
Problem solved.
You effectively have that already in V5R2, and in an improved form in
V5R3, where you can code a data structure result on externally described
I/O. In V5R2, you're limited to using LIKEREC data structures on record
name I/O. But in V5R3, you can also use externally described data
structures and LIKEDS DS's provided they can be linked back to the
record. Also, in V5R3 you can do this on file name reads, including the
ability to read by file name from multiple format logicals.

As another person said in this thread, RPGIV's inconsistencies are becoming
too difficult to teach inexperienced RPG IV programmers. This is just one
more item that contributes to that perspective.
I don't disagree. But as long as RPG programmers want progress, we have
to live with the inconsistencies. As you yourself pointed out, the data
structuring enhancements in V5 are the most useful and important
improvements to the language in a long time. But they are also a big
source of inconsistencies.
I may be just an idealistic dreamer, but I look forward to the day when
new RPG programmers no longer have to learn any of the old cruft in the
language.
Cheers! Hans
