RE: Channel Access Writes Failed on Asyn Record Writable Fields

["Mark Rivers" <rivers@cars.uchicago.edu>]

Glad it's working, but I don't understand the problem, because asyn
R4-10 should also work fine.

I finally got it working.  The problem turned out to be that there is 
something wrong with the asyn library my code was linking to.  After I 
linked my code to a different asyn library (R4-13), the asynRecord is 
working.  Thank you very much for your help.  I really appreciate it.
