Thank you all for the explanation.  That possibility hadn't occurred to me :-(

Please correct me if I'm wrong, but I think this should be clarified.  It
seems to me that there even more variations possible here than on an
80x86 :-)  I don't think you want to mention the grosser combinations, but:

1)  Can't the BV be used with either form of call?
2)  Mustn't the BE be used only with the LDIL form of call?
3)  Since the BE works with either intra- or interspace calls, is the LDIL
    call "better"?

In other words, wouldn't the explanation be a bit better if there were not
two "or"'s between the columns?

Thank you.  I'll be quiet now ;-)
