I am using Oracle on SCO386 Xenix and I wish to be able to be
able to retrieve a previous record.  I know that Oracle does
not inherently have such an operation, although I am mystified
as to why they don't.  Does anybody know of a way to emulate 
such an operation very effiently?  Maybe there is an undocumented
library call that somebody has found?  

Thanks in advance.
