Re: How much testing required after CVTRPGSRC?

I’m the wrong person to ask - I fought with them about this many many times while with IBM. Part of the issue was that with the various takeovers they were frequently in a “we’re going to dump this product” mode.

When they re-committed to it I had high hopes but nothing happened.

Their official line is that they convert “when it makes sense”. What they really mean is that they convert whenever a program becomes too big to compile with the old compiler. Their own programmers hate this - they know their life would be easier and less error prone if they converted the base - sadly their management can’t see the ROI. Personally I think that is nuts - the ROI would come in ease of enhancement and maintenance and of course making it look as if the product was not an ancient relic and giving their customers confidence in the future. I have met customers who have given up on JDE due to it being allowed to wither and age.

Sadly not enough of their customers care enough to beat up on them - but it is really sad. I know show that write at least 30%+ custom code where management force them o stay with RPG III even for new code because “If it’s good enough for JDE”.

They are not the only ones - and sadly IBM never pressured any of the ISVs to make the transition.

Ok - tiny rant over … back to work.

So why doesn't JDE just do this themselves and make it official? If a two-man team can do this over a weekend, what's their excuse?

Thanks

True - but given that the compiler has been available for over 21 years … well let’s just say that other than the documented differences (such as the aforementioned FREE op-code) there can be very few differences that have yet to be reported and fixed.

One simple example - entire JDE suite converted by one customer (two people) over a weekend. CVTRPGSRC threw up a couple of things that were easily remedied. They were fixed and a mass recompile submitted on Saturday. Sunday they resolved the couple of compile failures and tested. Monday the new version went into production. Zero problems reported.

You mileage may vary - and normally I’d want more testing than this but … compatibility was, and still is, a very high priority for the compiler team.
