The function <STRONG>field_opts_on</STRONG> turns on the given option bits, and leaves others alone. The function <STRONG>field_opts_off</STRONG> turns off the given option bits, and leaves others alone. The function <STRONG>field_opts</STRONG> returns the field's current option bits. The following options are defined (all are on by default): O_VISIBLE The field is displayed. If this option is off, dis- play of the field is suppressed. O_ACTIVE The field is visited during processing. If this option is off, the field will not be reachable by navigation keys. Please notice that an invisible field appears to be inactive also. O_PUBLIC The field contents are displayed as data is entered. O_EDIT The field can be edited. O_WRAP Words that do not fit on a line are wrapped to the next line. Words are blank-separated. O_BLANK The field is cleared whenever a character is entered at the first position. O_AUTOSKIP Skip to the next field when this one fills. O_NULLOK Allow a blank field. O_STATIC Field buffers are fixed to field's original size. Turn this option off to create a dynamic field.
