Displays the next structure at the current level, if one exists.
 Because NEXT is the default command, pressing the Return key is
 equivalent to executing a NEXT command.

    Format

      NEXT  [n]

1  –  Parameter

 n

    Specifies the number of times the structure pointer moves
    forward. You can use the optional parameter n instead of entering
    multiple NEXT commands. For example, the command NEXT 6 has the
    same effect as six NEXT commands (or pressing the Return key six
    times).
