.SH DESCRIPTION
The function \fBset_field_opts\fR sets all the given field's option bits (field
option bits may be logically-OR'ed together).
-
+.PP
The function \fBfield_opts_on\fR turns on the given option bits, and leaves
others alone.
-
+.PP
The function \fBfield_opts_off\fR turns off the given option bits, and leaves
others alone.

-The function \fBfield_opts\fR returns the field's current option bits.

-The following options are defined (all are on by default):
-.TP 5
-O_VISIBLE
-The field is displayed. If this option is off, display of the field is
-suppressed,

+Please notice that an invisible field
appears to be inactive also.
.TP 5
-O_PUBLIC
-The field contents are displayed as data is entered.
-.TP 5
-O_EDIT
-The field can be edited.
-.TP 5
-O_WRAP
-Words that don't fit on a line are wrapped to the next line. Words are
-blank-separated.
+O_AUTOSKIP
+Skip to the next field when this one fills.
.TP 5
O_BLANK
The field is cleared whenever a character is entered at the first position.

-Skip to the next field when this one fills
+O_EDIT
+The field can be edited.
.TP 5
O_NULLOK
Allow a blank field.
.TP 5
+O_PASSOK
+Validate field only if modified by user.
+.TP 5
+O_PUBLIC
+The field contents are displayed as data is entered.
+.TP 5
O_STATIC
Field buffers are fixed to field's original size.
+Turn this option off to create a dynamic field.

-O_PASSOK
-Validate field only if modified by user.
+O_VISIBLE
+The field is displayed.
+If this option is off, display of the field is
+suppressed.

+O_WRAP
+Words that do not fit on a line are wrapped to the next line.
+Words are
+blank-separated.
+.PP
+These extension options are defined (extensions are off by default):
+.TP 5
+O_DYNAMIC_JUSTIFY
+Permit dynamic fields to be justified, like static fields.
+.TP 5
+O_NO_LEFT_STRIP
+Preserve leading whitespace in the field buffer, which is normally discarded.
+.TP 5
+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.
+.TP 5
+O_INPUT_FIELD
+The \fBset_max_field\fP function checks for this extension,
+which allows a dynamic field to shrink if the new
+limit is smaller than the current field size.
.SH RETURN VALUE
Except for \fBfield_opts\fR, each routine returns one of the following:
.TP 5
-\fBE_OK\fR
+.B E_OK
The routine succeeded.
.TP 5

-System error occurred (see \fBerrno\fR).
+.B E_BAD_ARGUMENT
+Routine detected an incorrect or out-of-range argument.
.TP 5
-\fBE_CURRENT\fR
+.B E_CURRENT
The field is the current field.
