+The attributes are: height, width, row of
 upper-left corner, column of upper-left corner, number off-screen rows, and
 number of working buffers.

 The function \fBdynamic_field_info\fR returns the actual size of the field, and
-its maximum possible size.  If the field has no size limit, the location
-addressed by the third argument will be set to 0.  (A field can be made dynamic
