Choose the Annotate... menu item to create a line-by-line
  file listing of the changes made to each specified element
  generation; CMS places this file in your current default
  directory or a directory you specify.

  The annotate transaction documents the development of an
  element, and creates an output file that contains an
  annotated listing; unless you specify a different name,
  CMS names the file name the same as the element name and
  the file type is .ANN. The annotated listing file
  contains two parts:

  o  A history
  o  A source file listing

  The history includes the following:

  o  Generation number
  o  Date, time, user, and remark associated
     with each generation of the element

  The source file listing includes the following:

  o  All lines inserted or modified from
     generation 1 to the specified generation.
