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

  /SHOW[=(option[,...])]      D=/SHO=(NODAT,NODIC,NOINC,NOL,MAP,NOPRE,SIN)

  Controls listing file options.

  The /SHOW qualifier is ignored if /LIST is not specified, either
  explicitly or by default.  The /SHOW=NOMAP qualifier is ignored if
  /CROSS_REFERENCE is specified.

1 - DATA_DEPENDENCES

  Controls whether the listing file includes diagnostics about loops
  that are ineligible for dependence analysis, and loops that inhibit
  vectorization or autodecomposition.

  The DEC Language Sensitive Editor must be used to view the
  dependence diagnostic information.  See your performance guide for
  additional information.

2 - DICTIONARY

  Controls whether the listing file includes source representations
  of any CDD records referenced by DICTIONARY statements.

3 - INCLUDE

  Controls whether the listing file includes source lines from files
  or text modules specified in INCLUDE statements.

  The [NO]LIST option on the INCLUDE statement overrides the
  /SHOW=[NO]INCLUDE qualifier on the FORTRAN command line.

4 - LOOPS

  Controls whether the listing file includes loop structure and
  statement execution order chosen by dependence analysis, automatic
  decomposition, and vectorization.

  The reported loop structures can be scalar, vector, parallel
  section, parallel chunk, or serial.  The loop summary listing is
  described in greater detail in your performance guide.

5 - MAP

  Controls whether the listing file includes the symbol map.  If the
  /CROSS_REFERENCE qualifier is specified, MAP is ignored.

6 - PREPROCESSOR

  Controls whether the listing file includes preprocessor-generated
  source lines.

7 - SINGLE

  Controls whether cross-reference listings include the symbolic
  names of PARAMETER constants, even if they are not referenced
  outside the PARAMETER statements in which they are declared.

  The negative form, NOSINGLE, specifies that names of parameter
  constants be suppressed if they are only declared and not
  referenced elsewhere.  This is useful for cross-reference listings
  of small programs that specify INCLUDE declarations but use only a
  few of the parameter constant names that have been declared.

8 - ALL

  Requests that all optionally listed source lines and a symbol map
  be included in the listing file.  This is the same as specifying
  /SHOW without any arguments.

9 - NONE

  Requests that no optionally listed source lines or a symbol map be
  included in the listing file.  This is the same as specifying
  /NOSHOW.

  The default for the /SHOW qualifier is /SHOW=(NODATA_DEPEND,
  NODICT, NOINCLU, NOLOOP, MAP, NOPREPROCESS, SINGLE).
