Abbreviations

[David C. Allen]

I am trying to gather a list of Abbreviations that were used in the BUA_HAC 
from ECMguy's site. I am looking for help in understanding the ones with a 
???? after the Abbreviation. Also if I have entered a wrong meaning for the 
Abbreviation please email me with a correction.

Thanks

David
