 .SH DESCRIPTION
 The function \fBset_form_fields\fR changes the field pointer array of
 the given \fIform\fR.  The array must be terminated by a \fBNULL\fR.
-
+.PP
 The function \fBform_fields\fR returns the field array of the given form.
-
+.PP
 The function \fBfield_count\fR returns the count of fields in \fIform\fR.
-
-The function \fBmove_field\fR move the given field (which must be disconnected)
+.PP
+The function \fBmove_field\fR moves the given field (which must be disconnected)
 to a specified location on the screen.
-.SH RETURN VALUES
-The function \fBform_fields\fR returns \fBNULL\fR on error.
-
-The function \fBfield_count\fR returns \fBERR\fR (the general
-\fBcurses\fR error return value) on error.

+.SH RETURN VALUE
+The function \fBform_fields\fR returns a pointer (which may be \fBNULL\fR).
+It does not set \fBerrno\fP.
+.PP
+The function \fBfield_count\fR returns \fBERR\fR if the \fIform\fP parameter
+is \fBNULL\fP.
+.PP
 The functions \fBset_form_fields\fR and \fBmove_field\fR return one of
 the following codes on error:
 .TP 5
-\fBE_OK\fR
+.B E_OK
 The routine succeeded.

-\fBE_SYSTEM_ERROR\fR
-System error occurred (see \fBerrno\fR).
-.TP 5
-\fBE_BAD_ARGUMENT\fR
+.B E_BAD_ARGUMENT
 Routine detected an incorrect or out-of-range argument.
 .TP 5
-\fBE_POSTED\fR
+.B E_CONNECTED
+The field is already connected to a form.
+.TP 5
+.B E_POSTED
 The form is already posted.
 .TP 5
-\fBE_CONNECTED\fR
-The field is already connected to a form.
+.B E_SYSTEM_ERROR
+System error occurred (see \fBerrno\fR(3)).
