HP 48gII Graphing, 50g Graphing manual Nsub, →Num, …µNΣ

NOVAL is used to mark an empty field in a userdef ined 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 defaults for) some of the fields, use the NOVAL command.

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