</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
       The function <STRONG>set_form_opts</STRONG> sets all the given form's option bits  (form
       option bits may be logically-OR'ed together).

       The  function  <STRONG>form_opts_on</STRONG>  turns on the given option bits, and leaves
       others alone.

       The function <STRONG>form_opts_off</STRONG> turns off the given option bits, and  leaves
       others alone.

       The function <STRONG>form_opts</STRONG> returns the form's current option bits.

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

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

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


</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
       Except for <STRONG>form_opts</STRONG>, each routine returns one of the following:

       <STRONG>E_OK</STRONG> The routine succeeded.

       <STRONG>E_SYSTEM_ERROR</STRONG>
            System error occurred (see <STRONG>errno(3)</STRONG>).
