The CDFwalk program allows direct access to all variable data in a CDF. The data values of up to 27 variables may be displayed at once. (The CDF can have more variables but only 27 may be viewed at any one time.) The data value for each variable at a given record/indices location within the CDF conceptual view is displayed. The user can ``walk'' from one record/indices location to another sequentially (in any ``direction'') or a particular record/indices location can be ``jumped'' to directly. Variable values may also be used to directly ``jump'' to a record/indices location.
