Command_Parameters

element-expression

   Specifies one or more elements to be removed from one or more
   groups. 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 group does not contain the element being
   removed.)

group-expression

   Specifies the group from which one or more elements are to be
   removed. A group expression can be a group 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.
