For me, I would suggest to add some code before normal validation test!
(As Jim Booth mention)

But user may use Mouse to Click "Cancel" instead of press ESC...

In my view, if user make Empty String as return,
I would suppose user "Cancel Add/Edit" action, and thus tablereV()
with backing to non-add/edit status form interface.

Similarly, for printing, when user press "Cancel" on Getprint() function,
What I thought is user want to cancel Printing!

So, if Getprinter() return empty, Skip all printing coding!!
Else there will come an error if user click cancel on that dialog..

e.g. this code is simplest but suppose user not to click "cancel"

Set Printer to Getprinter()

but following code consider cancel button is pressed!

PR = Getprinter()

if Empty("&PR")
   Return
Else
   PrintJob
      * printing code ...
   EndPrint
Endif

P.S. the above code is based on VFP 5.0

for VFP 6.0, you can use Set("Printer", 3) to get back printer information!
