Hello,
 
I am working on an application where we are trying to remember previous
values from an execution of a Ruby program. Basically, we have a screen
where a user can type an 'X' into either a 'Yes' or a 'No' box. We do not
want them to type Xs into both boxes. So if the 'Yes' box has an X in it,
and then the user types an 'X' into the 'No' box, we want to clear the 'Yes'
box automatically. Our Ruby program runs each time the user tabs out of a
field on the screen or presses the Enter key.
 
Apparantly, Ruby does not have static variables where I can store the box
values and refer to them when the program runs again, if I could I would
setup state variables where I could compare the current state to the
previous state and see what has changed between executions and then take
appropriate action such as clearing a 'Yes' box because currently there is
an X in the 'No' box.
 
Any help would be greatly appreciated,
 
Thanks!
