Next question/problem. The folks working on z/TPF say that they have
ported the code to perform IUCV from TPF 4.1 to z/TPF and have made the
changes for mask bits and address requirements and do not get any IUCV
interrupts on the TPF machine. The other side is a CMS machine that acts
as a driver. It has not been altered in any way. I have asked the
obvious question about the IUCV DECLARE BUFFER and got a reply that was
an indignant "yes". And they have also unmasked by turning CR0, bit 62
on and unmasked the PSW. Do you have any idea why they would not receive
the IUCV interrupts?

Yes.
