Command_Parameters

element-expression

   Specifies one or more elements whose generations are to be
   modified. An element expression can be an element name, 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. Note that this parameter
   and the string on the /REMARK qualifier are unrelated.
