One thing for sure: it's spotty. A contact at IBM gets
absolutely EVERYTHING and was amazed that we had a hard
time getting IBIS models; another contact at a small
company was impressed at our ability to get anything at all.

Assuming you have access to 98.4, it's reported to be
massively bug-infested. Many of us *don't* have access to

Asking for license files for upgrades is beyond reason.
