Qualifiers

/APPEND
   Controls whether CMS appends the command output to an existing
   file, or creates a new file. If you specify /APPEND and the output
   file does not exist, CMS creates a new file. If you do not provide
   an output file specification (see the description for /OUTPUT),
   CMS searches your current default directory for a file with the
   file name specified in the file1 parameter and the file type .DIF.

/FULL
   Directs CMS to include a complete listing in the output file,
   including both identical and different generations between
   class1 and class2.

/IGNORE=(keyword[,...])
   Specifies one or more of the following keywords. Each keyword
   indicates a type of difference to be ignored during the
   comparison.

   Keyword          Ignored Difference

   FIRST_VARIANT    Directs CMS to ignore any differences where the
                    generation in one class is the first variant of
                    the generation in the other class. For example
                    generation 2C1 is a first variant of generation
                    2 and generation 4B6D1 is a first variant of
                    generation 4B6.

/LOG (D)
   Controls whether CMS displays success and informational messages
   on the default output device. By default, if the command executes
   successfully, CMS displays a success message. If you specify
   /NOLOG, success and informational messages are suppressed. Any
   warning, error, or fatal error messages are displayed regardless
   of whether /LOG or /NOLOG is specified.

/OCCLUDE[=option,...]
   Controls whether CMS selects the first instance of the specified
   object, or all instances of the specified object in the library
   search list. The options field contains one or more keywords
   associated with the name of the object. The options field can
   contain the following keywords:

      ALL--equivalent to (ELEMENT, CLASS)
      ELEMENT (D)
      NOELEMENT
      CLASS (D)
      NOCLASS
      NONE--equivalent to (NOELEMENT, NOCLASS)

   You can specify either ALL or NONE, or any combination of the
   [NO]ELEMENT and [NO]CLASS keywords.

   By default, CMS performs occlusion for all objects; that is, CMS
   selects only the first occurrence of a specified object.

/OUTPUT[=file-specification]
   Directs CMS to write output to the specified file. CMS creates a
   new file if you do not specify /APPEND. If you omit the /OUTPUT
   qualifier (or if you specify /OUTPUT but do not provide a file
   specification), CMS creates a file with the file name specified in
   the class1 parameter and the file type .DIF. If you specify a file
   name but omit the file type component, CMS writes the output to a
   file with the specified file name and a file type of .DIF.

/NOOUTPUT
   Directs CMS to execute a comparison without creating an output
   file. This form of the comparison may be significantly faster
   because CMS stops the transaction when it encounters the first
   difference.

/PARALLEL
   Controls whether the differing member generations from the two
   classes are formatted side by side. If you specify /PARALLEL,
   the differences from the first class are displayed on the left
   and the differences from the second class are displayed on the
   right. The heading of the differences report displays the class
   name of the first class on the left and the class name of the
   second class on the right.

   By default, the width of the listing is 132. Use the /WIDTH
   qualifier to control the width. Vertical lines separate the text
   on the left side of the report from the text on the right side.
   The text from each of the classes is allotted equal space (half
   the width of the full report).

   If a line from one of the classes being compared is longer than
   half the width of the full report, the line is truncated on the
   right. A plus sign (+) is printed at the end of the line to
   indicate that the line has been truncated.

/SHOW=(keyword[,...])
   Specifies one or more of the following keywords. Each keyword
   indicates a type of class difference to show.

   Keyword                   Difference Type

   GENERATION_DIFFERENCES    Directs CMS to show the difference if the
                             generation in one class differs from the
                             generation in the other class but one
                             generation isn't a variant of the other
                             generation.

   VARIANT_DIFFERENCES       Directs CMS to show the difference if the
                             generation in one class differs from the
                             generation in the other class and one
                             generation is a variant of the other. One
                             generation will be a variant of the other
                             if at some point in the path between one
                             generation and the other a generation is
                             reserved and replaced /VARIANT.

   If the /SHOW qualifier is not specified, both generation differences
   and variant differences are shown. If a generation of an element is
   in one class but no generation of the element is in the other class
   then the difference is always shown regardless of whether the /SHOW
   qualifier is specified or not.
/WIDTH=n
   Specifies the limit for the width of the differences report. The
   value n is required and must be an integer in the range 48 to 511. 
   If n is less than 48, 48 is used. If n is more than 511, 511 is 
   used. The default width is the same as the width of the output 
   device.

   The width of the report is rounded down to the nearest multiple
   of 8 minus 1. CMS rounds down so that if you have specified the
   /PARALLEL qualifier, CMS correctly interprets the horizontal tabs
   in the generation comment on the right. Thus, for example, if you
   specify a value of 100 on the /WIDTH qualifier, the actual width
   is 95.
