Here is the response from Nancy Wheeler, IBM

Subject: Problem with AP207
Hi Denny,
It's true, as originally shipped, the version of AP 207 for OS/2
returned 8 elements from WRITE and QWRITE. However, a customer
reported that this was inconsistent with other versions of AP
207, and after some deliberation, we decided we agreed that it
was an error. The reasons were that all the other AP 207's in the
world (DOS, AIX, Sun) return only 6 elements, and the original
documentation stated that 6 elements were returned. The error was
corrected in a CSD (CSD 8 I believe) to APL2 for OS/2. I imagine
you created your workspace running an older level and Mr. Erbe is
running a newer level. We apologize that the incompatibility of
this change has had an effect on your workspace. We surveyed our
internal IBM customers to see if anyone would object to the
change, none did.  And this is the first time anyone has noticed
it since the change was shipped. However, it is no less annoying,
I am sure. Regards,
Nancy Wheeler
