Adds the Systems class to the display.  Optionally, specific
  systems can be added to the display.  The systems to be added
  can be specified by type, system ID number, or node name.
  By default all systems are displayed.

  Format:  ADD SYSTEMS [/qualifier,...]

1  –  Qualifiers

1.1    /ALL

  Adds all the fields in the Systems class to the display.

  Format:  ADD SYSTEMS/ALL

1.2    /ID

  Specifies the system ID number of the system to be added to the
  display.  The system is assumed to be removed from the display
  via the REMOVE SYSTEMS/ID or /NODE commands.  To specify a
  hexadecimal value as the ID number, precede the value with %X.
  Optionally, ALL can be specified to restore all SYSTEMS that were
  previously removed via the REMOVE SYSTEMS/ID or /NODE commands.

  Format:  ADD SYSTEMS/ID=(system-ID[,...])
           ADD SYSTEMS/ID=ALL

  If only one system ID is specified, the parenthesis can be omitted.

  Examples:  ADD SYSTEMS/ID=101
             ADD SYSTEMS/ID=(206,%XF2A)

1.3    /NODE

  Specifies the node name of the system(s) to be added to the display.
  The system is assumed to be removed from the display via the REMOVE
  SYSTEMS/ID or /NODE commands. Optionally, ALL can be specified to
  restore all SYSTEMS that were previously removed via the REMOVE
  SYSTEMS/ID or /NODE commands.

  Format:  ADD SYSTEMS/NODE=(node-name[,...])
           ADD SYSTEMS/NODE=("node-name"[,...])
           ADD SYSTEMS/NODE=ALL

  If only one node name is specified, the parenthesis can be omitted.
  Quotation marks are optional except when specifying a system
  with a node name of "ALL."

  Examples:  ADD SYSTEMS/NODE=DARBY
             ADD SYSTEMS/NODE=("DARBY","DOOLEY","ALICAT","ALL")

1.4    /TYPE

  Specifies the type of system to be added to the display. Systems of
  the specified type are assumed to be removed from the display via the
  REMOVE SYSTEMS/TYPE command.  The type can be any of the valid system
  types as displayed in the HW_TYPE field prior to their removal. If the
  string which specifies the system type contains spaces, slashes or
  hyphens, then the string must be delimited by double quotation marks.
  If /TYPE=ALL is specified, then all nodes are added to the display.

  Format:  ADD SYSTEMS/TYPE=(system-type,"system-type"[,...])
           ADD SYSTEMS/TYPE=ALL

  If only one system type is specified, the parenthesis can be omitted.

  Examples:  ADD SYSTEMS/TYPE="VAX 8650"
             ADD SYSTEMS/TYPE=(HS90,"VAX 8800")
