Save in Standalone

[Roger Guay]

Thanks, Graham.  Makes sense now that I think about it.  By a "data 
stack" you must mean a   .rev  stack, as a standalone data stack would 
have the same problem???  And, since I can't expect my users will have 
Revolution installed on their machine, I guess I'll have to use 
external files to save to and pull from?

Thanks, Roger
