Elyse,

I was about to post almost exactly what "Fast Eddie" posted, but, as usual, he beat me to it.

There was one point he made I'd take issue with. If I understood him correctly, he suggested a logical for each page to let you know whether or not a value on the page had changed. If that's the case, that's a lot unnecessary overhead. What you can do is create a numeric property on the frame or form, initially set to zero. Then create a method, passing the page number to it, as a numeric parameter to change the value. The code might look something like this:

LPARAMETER pnpagenum

This.PageFlags = BITOR(This.PageFlags, 2 ^ (pnpagenum - 1))

When you need to find out if a value on any page has been changed, loop through the PageFlags and test using BITTEST(), like this:

FOR lni = 0 TO 31
IF BITTEST(This.PageFlags, lni)
* Something was changed.
ENDIF
ENDFOR

Of course, if there are more than 32 pages, you'll have to create a second set of flags.
