Full Command and Function Reference 3-157
NOVAL is used to mark an empty field in a user-defined dialog box created with the INFORM
command. INFORM defines fields sequentially. If default values are used for those fields, the
defaults must be defined in the same order as the fields were defined. To skip over (not provide

After INFORM terminates, NOVAL is returned if a field is empty and OK or ` is selected.
