-<H2>RETURN VALUE</H2><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>

- <STRONG>NOTES</STRONG> The header file <STRONG><form.h></STRONG> automatically includes the
- header file <STRONG><curses.h></STRONG>.
+ O_STATIC
+ Field buffers are fixed to field's original size. Turn this
+ option off to create a dynamic field.
+ O_VISIBLE
+ The field is displayed. If this option is off, display of the
+ field is suppressed.

-<H2>PORTABILITY</H2><PRE>
- These routines emulate the System V forms library. They
- were not supported on Version 7 or BSD versions.
+ O_WRAP
+ Words that do not fit on a line are wrapped to the next line.
+ Words are blank-separated.
+ These extension options are defined (extensions are off by default):
-</PRE>
-<H2>AUTHORS</H2><PRE>
- Juergen Pfeifer. Manual pages and adaptation for new
- curses by Eric S. Raymond.
-
+ O_DYNAMIC_JUSTIFY
+ Permit dynamic fields to be justified, like static fields.
+ O_NO_LEFT_STRIP
+ Preserve leading whitespace in the field buffer, which is normally
+ discarded.
+ O_EDGE_INSERT_STAY
+ When inserting into a field up to the boundary position,
+ optionally delay the scrolling, so that the last inserted
+ character remains visible, but advance the cursor to reflect the
+ insertion. This allows the form library to display the inserted
+ character in one-character fields as well as allowing the library
+ to maintain consistent state.
+ O_INPUT_FIELD
+ The <STRONG>set_max_field</STRONG> function checks for this extension, which allows
+ a dynamic field to shrink if the new limit is smaller than the
+ current field size.
