1  RESERVE
   Reserves an element in your current CMS library.

   Format

     RESERVE   [element-name]

2  Qualifiers

/GENERATION

      /GENERATION[=generation-exp]

   Specifies the generation of the element to reserve. If you do
   not specify a value, LSE assumes you have specified generation
   "1+" (the generation-exp parameter must be enclosed in quotation
   marks if nonalphanumeric characters are present). If you omit
   the qualifier altogether, LSE uses the specified or default value
   from the command SET CMS/GENERATION to determine the generation to
   reserve.

/MERGE

      /MERGE=generation-exp
      /NOMERGE (D)

   Determines whether LSE merges another generation of the element
   with the generation being reserved. If you omit this qualifier,
   LSE uses the setting of the command SET CMS/[NO]MERGE to determine
   whether to merge generations of the element being reserved.

   You must enclose generation-exp in quotes (" ")  if
   nonalphanumeric characters are present.

2  Parameter

element-name
   Specifies the elements to reserve. If you do not specify an
   element name, LSE uses the file name and type of your current
   buffer as the element name.
