VMS Help FORTRAN, /ANALYSIS_DATA  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  /[NO]ANALYSIS_DATA[=file-spec]        D=/NOANALYSIS_DATA

  Directs the compiler to produce an analysis data file that contains
  cross-reference and static-analysis information about the source
  code being compiled.

  The default file name is the name of the primary source file; the
  default file type is ANA (that is, filename.ANA).

  Analysis data files are reserved for use with Compaq products such
  as, but not limited to, the DEC Source Code Analyzer (SCA).

  The compiler produces one analysis file for each source file that
  it compiles.  If you are compiling multiple files and you type in a
  file name, each analysis file is given that name (with an
  incremental version number).

  If you do not specify the /ANALYSIS_DATA qualifier, the default is
  /NOANALYSIS_DATA.

  If you request the /DESIGN=COMMENTS qualifier along with the
  /ANALYSIS_DATA qualifier, the compiler places additional
  information in the SCA analysis data file.

  The /DESIGN=COMMENTS qualifier causes the compiler to scan for
  program design information in comment text and include this
  information in the SCA analysis data file.  Also, the
  /DESIGN=PLACEHOLDERS qualifier causes the compiler to put
  information about placeholders used into the SCA file.  You can
  then use SCA and LSE commands to retrieve the design information
  from the file.
