SPARK isn't Ada nor is it an approach the makes sense for most programming = tasks. He could also just write those sections in other proof base language= s. I wonder if SPARK is even the best choice today for that purpose. EGarrulo, your question is not a language question but a design question. W= hat you want can be done in any language and depending on what you are tryi= ng to "roll back" I can think of many many ways to do it. Be specific and I= 'm sure some of us can offer advice for your project. David Botton
