   int form_opts_off(FORM *form, Field_Options opts);

DESCRIPTION

   The function set_form_opts sets all the given form's option bits  (form
   option bits may be logically-OR'ed together).

   The  function  form_opts_on  turns on the given option bits, and leaves
   others alone.

   The function form_opts_off turns off the given option bits, and  leaves
   others alone.

   The function form_opts returns the form's current option bits.

   The following options are defined (all are on by default):

   O_NL_OVERLOAD
        Overload  the REQ_NEW_LINE forms driver request so that calling it
        at the end of a field goes to the next field.

   O_BS_OVERLOAD
        Overload the REQ_DEL_PREV forms driver request so that calling  it
        at the beginning of a field goes to the previous field.

RETURN VALUE

   Except for form_opts, each routine returns one of the following:

   E_OK The routine succeeded.

   E_SYSTEM_ERROR
