>A form method can be added to any form - it's just a method like 'Click' or 'SetFocus'. You name it, add you own code and call it like any of the 'built-in' methods. Go to Form/Method on the menu and follow the screen directions. It will show up below the standard events/methods.

I see that. How is the method invoked. I've done all my programming to this point by manipulating the events on controls. when you said:

"I'd write a form method disabling and enabling the cmdbuttons. The disable version would be called when either textbox1 or textbox2 is live. Re-enabling is called from the VALID or LOSTFOCUS methods, but ONLY if there were good values in both textboxes."
do you mean you'd process the events for the controls thru the form method?
By hard coding using code like "setall." ..." etc?
