FourGen: undo changes on field level

Hi FourGener's Our users want to have a hot key to undo changes a user has done while working with the single INPUT field not entire INPUT statement. I know that the initial value of the field is stored into prev_data. Surely, in particular case I can do let p_example.field=prev_data This means for every form I have to create custom function which includes case statement with all screen fields. I guess this will work but it's so tedious to create and support. I'd rather like to have a library function which would set current p_.field to prev_data. Any suggestions will be appreciated. --------------------------------------------------------------- Vadim G.
