      module name           symbols   size

      DBG>

      In this example, the SHOW MODULE command, without a parameter,
      displays information about all of the modules in the current
      image, which is the main image by default. This example shows
      the display format when all modules have the same source
      language. The symbols column shows that module TEST has been
      set, but module SCREEN_IO has not.

    2.DBG> SHOW MODULE FOO,MAIN,SUB*
      module name           symbols   language   size

      total modules: 4.     bytes allocated: 60720.
      DBG>

      In this example, the SHOW MODULE command displays information
      about the modules FOO and MAIN, and all modules having the
      prefix SUB. This example shows the display format when the
      modules do not have the same source language.

    3.DBG> SHOW MODULE/SHARE
      module name           symbols   language   size

      DBG> SET MODULE SHARE$SHARE2
      DBG> SHOW SYMBOL * IN SHARE$SHARE2

      In this example, the SHOW MODULE/SHARE command identifies all
      of the modules in the current image and all of the shareable
      images (the names of the shareable images are prefixed with
      SHARE$. The SET MODULE SHARE$SHARE2 command sets the shareable
      image module SHARE$SHARE2. The SHOW SYMBOL command identifies
      any universal symbols defined in the shareable image SHARE2.
