Command_Parameters

element-expression

   Specifies one or more generations of elements to be removed from
   one or more classes. An element expression can be an element
   name, a group name, a wildcard expression, or a list of these
   separated by commas. When you use wildcard characters in the
   element expression, /IF_PRESENT is the default. (CMS does not
   return an error message if the class does not contain a generation
   of the element.)

class-expression

   Specifies the class from which the element generation is to
   be removed. The class must not have read-only access. A class
   expression can be a class name, a wildcard expression, or a list
   of these separated by commas.

remark

   Specifies a character string to be logged in the history file
   with this command, usually used to explain why the command was
   entered. The remark is enclosed in quotation marks. If no remark
   was entered, a null remark ("") is logged.
