  35 .SH DESCRIPTION
  36 .LP
  37 \fBnew_field()\fR creates a new field with \fIr\fR rows and \fIc\fR columns,
  38 starting at \fIfrow\fR, \fIfcol\fR, in the subwindow of a form. \fInrow\fR is
  39 the number of off-screen rows and \fInbuf\fR is the number of additional
  40 working buffers. This routine returns a pointer to the new field.
  41 .sp
  42 .LP
  43 \fBdup_field()\fR duplicates \fIfield\fR at the specified location. All field
  44 attributes are duplicated, including the current contents of the field buffers.
  45 .sp
  46 .LP
  47 \fBlink_field()\fR also duplicates \fIfield\fR at the specified location.
  48 However, unlike \fBdup_field()\fR, the new field shares the field buffers with
  49 the original field. After creation, the attributes of the new field can be
  50 changed without affecting the original field.
  51 .sp
  52 .LP
  53 \fBfree_field()\fR frees the storage allocated for \fIfield\fR.
  54 .SH RETURN VALUES
  55 .LP
