SYNOPSIS

10       #include <form.h>
11       int set_form_opts(FORM *form, Field_Options opts);
12       int form_opts_on(FORM *form, Field_Options opts);
13       int form_opts_off(FORM *form, Field_Options opts);
14       Field_Options form_opts(const FORM *form);

DESCRIPTION

17       The function set_form_opts sets all the given form's option bits  (form
18       option bits may be logically-OR'ed together).
19
20       The  function  form_opts_on  turns on the given option bits, and leaves
21       others alone.
22
23       The function form_opts_off turns off the given option bits, and  leaves
24       others alone.
25
26       The function form_opts returns the form's current option bits.
27
28       The following options are defined (all are on by default):
29
30       O_NL_OVERLOAD
31            Overload  the REQ_NEW_LINE forms driver request so that calling it
32            at the end of a field goes to the next field.
33
34       O_BS_OVERLOAD
35            Overload the REQ_DEL_PREV forms driver request so that calling  it
36            at the beginning of a field goes to the previous field.
37
