The ANNOTATE command documents the development of an element. This
    command creates an output file that contains an annotated listing;
    by default, the file name is 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 generation number, date, time, user,
    and remark associated with each generation of the element (and
    other file-related information when you use the /FULL qualifier).
    The generations are listed in reverse chronological order. The
    generation numbers of the specified generation and its ancestors
    are marked with an asterisk (*).

    The source file listing contains all the lines inserted or
    modified from generation 1 to the specified generation. The
    listing does not show lines deleted from the file. CMS inserts
    consecutive line numbers in the listing unless editor-assigned
    line numbers already exist. (The line numbers start with 1 for the
    first line and increase by 1 for each line.) The generation field
    starts at the first character position of each line. It contains
    the generation number of the most recent generation in which the
    line was inserted or modified. The generation field is blank if a
    line is unchanged since generation 1.
