RE: When is %EOF not an %EOF

My understanding of this is the ReadE basically generates the same code as a
Chain.  Chain is a random I/O operator and will not allow record blocking to
occur.  There's a compiler info message about record blocking that
disappears when you use ReadE on a file.

Does someone have an explination of the performance difference? 
I can understand that there would be a small performance hit with the ReadE
(< 5%) over Read but >10% just seems wrong.

WOW.  I am absolutely floored.  With a single-field key, READ/compare is
about 10% faster than READE.  Who'd'a thunk?
