Thanks very much Bob, you got it right in one. :o)

It's a source of constant amazement the multitude of
ways I stuff things up! Would you believe I quickly
added the VRCON/PIE1 chunk just before my first test,
in anticipation that I might have F628 compatibility
problems! No that's not my normal way of bank switching.

This list is great, I should buy another PicList mug. :o)
