<H2>SYNOPSIS</H2><PRE>
<STRONG>#include</STRONG> <STRONG><form.h></STRONG>
int set_form_opts(FORM *form, Field_Options opts);

<H2>DESCRIPTION</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>RETURN VALUE</H2><PRE>
Except for <STRONG>form_opts</STRONG>, each routine returns one of the fol-
lowing:
<STRONG>E_OK</STRONG> The routine succeeded.
<STRONG>E_SYSTEM_ERROR</STRONG>
System error occurred (see <STRONG>errno</STRONG>).

The header file <STRONG><form.h></STRONG> automatically includes the header
file <STRONG><curses.h></STRONG>.
</PRE>

were not supported on Version 7 or BSD versions.
