      .SHOW [argument-list]
      .NOSHOW [argument-list]

    argument-list

    One or more  of  the  optional  symbolic  arguments;  BINARY,
    CALLS, CONDITIONALS,  DEFINITIONS,  and  EXPANSIONS.  You can use
    either the long form or the short form of  the  arguments.   You
    can  use  each argument  alone  or in combination with other
    arguments, but you must separate them by commas, tabs, or spaces.

    You can use .SHOW and .NOSHOW with or without an argument list.
