@@ -48,31 +48,41 @@ int free_field(FIELD *field);
 The function \fBnew_field\fR allocates a new field and initializes it from the
 parameters given: height, width, row of upper-left corner, column of upper-left
 corner, number off-screen rows, and number of additional working buffers.
-
+.PP
 The function \fBdup_field\fR duplicates a field at a new location.  Most
 attributes (including current contents, size, validation type, buffer count,
 growth threshold, justification, foreground, background, pad character,
 options, and user pointer) are copied.  Field status and the field page bit are
 not copied.
-
+.PP
 The function \fBlink_field\fR acts like \fBdup_field\fR, but the new field
 shares buffers with its parent.  Attribute data is separate.

+.PP
 The function \fBfree_field\fR de-allocates storage associated with a field.
 .SH RETURN VALUE
 The function, \fBnew_field\fR, \fBdup_field\fR, \fBlink_field\fR return

 These routines emulate the System V forms library.  They were not supported on
 Version 7 or BSD versions.

 It may be unwise to count on the set of attributes copied by
