  /NOSHOW

  Specifies a list of items to be included in the listing file.  A
  single   identifier   or  a  list  of  identifiers  enclosed  in
  parentheses may follow /SHOW; these identifiers are the names of
  options  that  inform  the compiler which type of information it
  should generate.  The options are as follows:

     ALL
       Enables listing of all options.

     NONE
       Disables all /SHOW options.

     [NO]DICTIONARY
       Enables listing of %DICTIONARY records.

     [NO]HEADER
       Enables page headers.

     [NO]INCLUDE
       Enables listing of %INCLUDE files.

     [NO]INLINE
       Enables listing of inline summary (OpenVMS VAX)

     [NO]SOURCE
       Enables listing of VSI Pascal source code.

     [NO]STATISTICS
       Enables listing of compiler statistics.

     [NO]STRUCTURE_LAYOUT
       Enables listing of variable and type layout.

     [NO]TABLE_OF_CONTENTS
       Enables listing of table of contents only if the %TITLE or
       %SUBTITLE directive was specified in the source code (OpenVMS
       VAX)

  On  OpenVMS  VAX  systems,  the  inline  summary,   enabled   by
  /SHOW=INLINE,  shows  only  the  names  of  routines  that  were
  expanded inline in the compilation.  If you  want  to  know  why
  routines   were   not  expanded  inline,  you  must  specify  an
  additional qualifier, either /OPTIMIZE=INLINE or  /OPTIMIZE=ALL.
  Although  /OPTIMIZE  defaults to /OPTIMIZE=ALL, you must specify
  ALL to generate these reasons.

  The compiler ignores the /SHOW qualifier  if  you  do  not  also
  specify  the  /LIST  qualifier  on  the  same  command line.  On
  OpenVMS VAX systems, the default  for  the  /SHOW  qualifier  is
  /SHOW=(DICTIONARY,    HEADER,   INCLUDE,   SOURCE,   STATISTICS,
  TABLE_OF_CONTENTS).  On OpenVMS Alpha and OpenVMS  I64  systems,
  the  default  for  the  /SHOW  qualifier  is  /SHOW=(DICTIONARY,
  HEADER, INCLUDE, SOURCE, STATISTICS).

  The negation /NOSHOW is  equivalent  to  /SHOW=NONE.   /SHOW  is
  equivalent to /SHOW=ALL.
