Gordon,
thanks for your response. I am aware of the time 
compression capability of Stephane's DLL. However applying that DLL it is not 
possible according  to my understanding to use these time-compressed 
data and  apply any of the AB functions automatically. Of course one 
can do all that by programing specifically for ones needs. But that is not the 
idea. I my view there ought to be a functionality in the programing interface of 
AB to switch timebases.
 
Al

  frames in automatic analysis
  Hi Al,I would grab the compiled archives of this 
  newsgroup from the AB site. Time compression is widely discussed and 
  Tomasz points out several issues as it relates to time compression. You'll 
  get the most out of those posts, since the topic has already been so well 
  discussed in the past.That said, a gentleman by the name of 
  Stephane wrote a DLL which is apparently in the files area and which 
  offers a number of neat additions to AB (Darvas boxes, etc.). I haven't 
  used it personally, but I'm aware that one of the things it deals with is 
  time compression.Good luck.Gordon--- In
