<H2>DESCRIPTION</H2><PRE>
The function <STRONG>set_field_opts</STRONG> sets all the given field's
option bits (field option bits may be logically-OR'ed
together).
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 don't 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.
O_PASSOK
Validate field only if modified by user.
</PRE>

Except for <STRONG>field_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</STRONG>).
<STRONG>E_CURRENT</STRONG>
