Alias and Buffering

[John Stires]

We had a lively discussion this morning concerning aliases in Quick, QTP and QUIZ.  At issue was the idea that if you use an ALIAS, as in a file statement in QDESIGN, you cause the program to buffer the file twice instead of once.  My boss was pretty adamant that a consultant from COGNOS was here some years ago and firmly told her about this extra buffering.  
   
  Can that be true?  My thinking has always been that the ALIAS merely caused a minor cross reference or name translation within the program and nothing at all to do with file buffering or any other over head.
   
  What is your say?
   
  Thanks,
