node at (info "(forms)Control File Format"). The text

     If the control file does not set ‘forms-format-list’ a default format
  is used.  In this situation, Forms mode will deduce the number of fields
  from the data file providing this file exists and
  ‘forms-number-of-records’ has not been set in the control file.

should read
